Ok I've been gatting this too much lately, it happens when I already connect to a server, it says "Kicked via Punkbuster Corrupted file/memory [81055]", what can be the problem, I tried googling, but all I came up were some Hungarian and Czech forums...

Well Punkbuster is an anti-cheating program. Make sure you don't have any mods runnig ar anything.

I don't have any mods runing, and it's really wird it appeared on 90% of servers today, no matter from where, and yes I have patch the ga,e and everything, and it didn't show that message so often before(it only showed 1-2 times before, but just today 10)...

Well..... I realize you have internet access restrictions. Try to download a new version of the game or punkbuster itself.

Nope dude the version is 1.5(latest CoD patch) and punkbuster is the whichever one came with it, and it all worked fine a day ago...
