''DISCONNECT FROM SERVER'' problem[SOLVED]

i got the message disconnect from server
but i'm not banned it comes automaticelly
why does it not works?
i got windows 7 yesterday i could play
but today not :S
and i have all things you need downloaded.
and when i don't use the hack it does it again...

Hmm...I really don't know what to tell you. Check your internet. "Disconnected"

i checked it's not that problem :P
