CoDUO Server Errors Helpdesk
I noticed that there are quite some players who have issues with connecting the server / playing the server.
As they sometimes do not know how to fix them, or avoid them, I decided to make this post.
I will be handling all the CoDUO errors and how to fix them.
If you noticed an error is missing, please contact me and I'll update the guide.
Please also report any mistakes or improvements!
NOTE: Only handling MULTIPLAYER-Errors! For SINGLEPLAYER-Errors, please search google.
Your CoD UO MP does not start
This error is when you keep opening your CoDUO by pressing your desktop-link but it does not open.
Option 1: Link problem
Option 2: Process Glitch
You cannot find any servers
This error means when opening you CoDUO, and when you wish to select your server, your list is empty.
Option 1: Check your connection
Option 2: Check your Multiplayer settings
Option 3: Your server list is glitched
Option 4: Your server list is filtered
Could not load ........ .pk3
This is an error that is caused when you try to load a modded server. The error means that the server is unable to load a modded item. These can be weapon files / texture files / vehicle files. It disconnects you from the server.
This error can occur sometimes when connection to new servers. It resets your CoD UO folder to standard, which sets the downloading on "NO".
Option 1: Your downloading is OFF
CD-Key Error
This error occurs while loading your server. It disconnects you from the server.
This means that there is a glitch with your CD-Key.
This error is rather rare.
Option 1: Re-type your CD Key
Option 2: Your CD-Key is being used
If you have the game installed on two different devices with the same CD-Key & try using it at the same time, this error will occur. You can only use the CD-Key for ONE device at the SAME time. It is possible to install the key for multiple devices and even play. Only not at the same time. So kick that other person from his device so you can play.
If you use internet keys, well kiss my *BLEEP* and buy the game like a real gamer!

This error occurs while loading the server. It can happen to modded or un-modded servers. It disconnects you from the server.

Server Command Overflow
This error occurs while playing. It disconnects you from the server.
This is caused by your Hunkmegs.

How to solve?

Server Disconnected
This error occurs while playing / loading / downloading. It disconnects you from the server.
This error only occurs by actions of the server developer(s). It is extremely rare for the error to occur without interference from the developer(s).
How to solve?
Actually, this is one of them errors that cannot be fixed. This error is almost always caused by actions due to the servers developer. Eg. when Fabio restarts the server, all the players will get this error. It's extremely rare that you get this error by others reasons then the developers actions. Sadly enough, there is nothing we / you can do about them.

Your CoD UO MP does not start
This error is when you keep opening your CoDUO by pressing your desktop-link but it does not open.
Option 1: Link problem
- Right Click on your desktop icon,
- Select properties,
- Double check if it is correctly linked to your main folder in your C: drive,
- If not, copy the link and replace it. OR, remove the former link on your desktop and create a new one.
- If this does not solve your problem, please scroll down.
Option 2: Process Glitch
- Open Task Manager,
- Go to the Processes tab,
- Search for CoDUOMP.exe,
- Delete the process (this does not removes your game. It forces it to stop.),
- Restart your MP.
- If it does not work, reboot your notebook / desktop.
- If it does not work after the reboot, I suggest reinstalling the game as I believe some of your main files might be missing.
