Call of Duty United Offensive Multyplayer

[Baron]

OK, I have a little problem. Me and some friends want to play COD UO, but we encounter a very known problem. Every time we try some of us gets the message "CD key in use. Please try again later". Now we all have different CD keys, for Call of Duty and the expansion pack. Some of us are using the same internet provider, and we can see the created game in LAN, the others connect using the console, with "connect (IP)". Any solution to this?
Thanks in advance

May need to:

A: Upate PunkBuster using the Setup tool located HERE (http://websec.evenbalance.com/downloads/windows/pbsetup.exe)

B: Reinstall/Repair the Punkbuster Service using the tool found HERE (http://www.evenbalance.com/downloads/pbsvc/pbsvc.exe)

Run them both then see of that helps with the issue. Also, if you are both trying to play on LAN, that may be conflicting. If your running a server locally, you will need to add your local IP to the PB config file as a whitelist entry.

Anyhow, let me know if that helps.

Fixed the problem with a private server patch :) It runs fine now

Then it was PB conflict due to running locally. You know you can just add your local IP to the PB config to fix that right? Private Server works, but you would be letting illegal cd-key players in if you do it that way (assuming you run the server public) Also, you will have a hard time keeping cheaters out with a private server version since PB cannot do its job properly.
