A)  The server is down or is restarting.
B) If the server is up and you have this error, try allowing LucianMS in your firewall/antivirus settings.
C) You are not connected to the internet.

D) Your antivirus, firewall, or other security programs may be blocking LucianMS from working correctly.

Although you may have made an exception for LucianMS in the past, it is possible that an update changed enough so that it is no longer recognized by your security software.

For troubleshooting purposes, temporarily disable such programs as a test to see if there is a setting that needs to be adjusted for LucianMS to run properly. Do this even if you have added LucianMS to the exception or ignore list, as you may have overlooked something.

If disabling worked, it is recommended that you properly add LucianMS to the exceptions or ignore list for that security program.

E) The Microsoft Loopback Adapter can interfere with the game. If you have played on a MapleStory private server you most likely have this.

   On the Start Menu, right-click "My Computer" or "Computer" and select "Manage"
   In the left side window pane, select "Device Manager"
   In the Device Manager window, expand the "Network adapters" section
   Locate "Microsoft Loopback Adapter", right-click, then select "Disable" from the context menu
   You may have to reboot your PC to see the changes take effect.

If you do not have "Microsoft Loopback Adapter" listed there, then you simply don't have it. Also, all Loopback adapters must be disabled should you have more than one.  

A) Make sure your LucianMS client  is inside of your LucianMS folder.
B) Download the v83 setup and install it to an empty folder & then put your LucianMS files there.

This error means that the installation files are corrupted.

There are several reasons as to why this may happen:

A) Your system might be unstable or an application might be interfering with the installation process. Reboot your computer and try installing the game again.

B) Your Temporary Internet Files may need to be cleared.
- For Internet Explorer users: Click on “Tools”, select “Internet Options” and click on “Temporary Internet Files” (or “Delete…”) from the “General” tab. Select “Delete Files”.
- For Firefox users: Click on “Tools”, select “Clear Private Data” and then click   on  “Clear Private Data Now”.
Note: This may take several minutes. Once it’s done, download LucianMS again.

C) Your download manager could be corrupting the downloaded files. If you have a software that you use to manage or accelerate your downloads, we suggest that you turn it off and download LucianMS without it.

D) Another possible cause of this error code could be your antivirus. Sometimes your antivirus will end up mistaking the client for a virus, and will delete it. You'll need to add the file as an exception to your antivirus, or turn it off.

MapleStory is compatible with Vista computers. Many users have issues on Vista because some privilege settings interfere with the game running or installing. The first step is to check your privilege settings.

To do so, right-click the LucianMS client, then: Properties → Compatibility tab → check "Run this program in compatibility mode" → select "Windows XP".

This error is caused by a missing WZ file in your LucianMS folder.

This error can also happen if you are using files from other sources than what is available from the LucianMS website.

You may be running the game in compatibility mode.
Compatibility Mode is a software mechanism in which the program you are running either emulates an older version of software, or mimics another operating system in order to allow obsolete or incompatible software or files to remain compatible with the computer's newer hardware or software.

What this means is old or outdated files may be accessed or that the emulation process is not working, which can cause the game not to load.

To resolve this make sure your game is not in compatibility mode and if it is, take it out of compatibility mode.

Here is how you do it:

1) Right-click on the program icon and select the Compatibility tab.

2) Click on the small box within Compatibility mode and remove any check over “Run this program in compatibility mode for:"

3) Click Apply.

4) Click OK.

5) Relaunch the game.

Solution: For Windows XP:

1) Press "Windows Key" & R The Run box should now appear.
2) Type "cmd.exe" in the box and click "OK".
3) Type "ipconfig /flushdns" and press "Enter" on your keyboard.
4) Then type: netsh winsock reset, and then press "Enter" on your keyboard.
5) Reboot your PC.

For Windows Vista / 7 / 8:

1) In the start menu search bar, type "cmd", now "cmd.exe" should be one of the first things on the list to appear.
2) Right-click "cmd.exe" and select "Run as administrator".
3) Type "ipconfig /flushdns" and press "Enter" on your keyboard
4) Then type: netsh winsock reset, and then press "Enter" on your keyboard
5) Reboot your PC.

This error may happen randomly or you stayed in the cash shop for too long. Just start LucianMS again. Some skills can also cause this error.

If restarting LucianMS doesn't work, then I suggest you restart your computer and then close any startup programs you have active after the reboot.

1)[/b] Run the client as admin (for vista & win 7 users)
2) If other players can get online, disable your loopback adapter.
3) If the problem still persists, wait for a server restart (Server login is probably down).

Most common cause of this is, that you have installed the v83 files into the same folder where your GMS or other versions are saved. Make a new folder on the desktop or wherever you want and name it something like LucianMS. Now, install the v83 files into the new folder, put the LucianMS files & client in the same folder, and then login. If this doesn't work, your account might be deleted.

When using a cable modem this happens when the DHCP client on the PC hangs. To fix this you usually power cycle the modem (remove power, wait a few seconds and plug it back in). Then you will get "not a socket" error when trying to renew the IP address. So all you have to do is reset winsock. Either by deleting the reg keys or by typing: netsh winsock reset catalog in cmd

One of your files in is corrupted/missing.

Re-download LucianMS from the website. Put them all in one folder that has no other Maplestory clients except LucianMS.


Reinstall from the download page (Link to the download page at the bottom).

This error occurs shortly after launching the client and can be caused by a compatibility registry key for a library maplestory loads. It is fixed by removing the registry key.

The registry key is located at "HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers", and contains a value with the name consisting of the path to your maplestory.exe, and the Data being something similar to "$~ IgnoreFreeLibrary<nmconew.dll>". The dll can vary. Deleting the value fixes the issue.

For those who have never used the registry editory just press the windows key and type regedit and press enter to start it up

If this does not work or you can't find it, then reinstall from the download page (Link to the download page at the bottom).
