I cant play any servers without this crap kickin' me off at the loadin' screen
any help is necessary.
Please do not rage me with "your a noob" and stupid comments Thx

I'm on windows xp ^^

lol i've the same problem when i try a new server it doesn't update and when u start it tells antihack error

I had that shit happening, I just did a system recovery to an earlier time and then every worked fine.

That error occurs if you dont have the right files of engine.exe / config.pk3 / e.pk3
means the files exist but its checksum is wrong so u get kicked for "probably hacking".
To prevent that you need to get the most latest files of the ones mentioned.
As updaters update often the same files the system looks them up first in temporary internet files. If the updater finds 'em there it doesn't download the most actual file and uses the temp file instead that might be not the newest file. To stop that you need to clean you temp files on your own or with tools easy to find on the web.
