in game error!!!

[gamershome]

hi guys i got the following problem:

i made a new engine.exe, installes kosp etc.... when i am on the server select screen evrythings fine, but when i click on the login button the game kicks me and it says: undefinied files installed - please reinstall the game. I can not even write my login name or something...


my problem is i don't know whats wrong...i've done everything right. And why does the game start and the error comes only in game??? Normaly it must appear when ahn hackshield starts...or not???
