Call Of Duty: Unpure client error
 

Hi, I never had any problems installing an playing COD until I bougth the United Offensive expansion pack and installed it. Basically, when running in single user I have no problem. It is only when I trry to play multiuser and it tries to load a map ( any map, even the old ones ). Then it gives me this error:

Unpure client detected. Invalid
.PK3 files referenced!
Z:\home\user\cod\uo\pakuo00.pk3

Does anyone has any idea? I tried searching this and other forums and found nothing that really deals with the same problem that I have. A few of them where close, but the soulutions did not applied to me.

Thanks,
Figa

More info just in case:

The game works fine under windows, so the files or cds are not corrupt. I guess it might be something with files permission or maybe the loki installer put something wrong somewhere.

If anybody has any ideas, do not hesitate to say it. Ill try anything. I hate having to get out of Linux to boot into windows to play only multiuser.
