Hello Kalath....
First of all, the question is.... you've just been Kicked or did you get Banned?
If you've just been Kicked it sould be possible to reconnect after one Minute.
To get Kicked from the Server might have many reasons... To Long inactive in Game, to high Ping,
Outdated Punkbuster Signatures, ect.
If you get banned from Server..... you are one of the Bad Guys
The Server banns Teamkilling for to many times, Basecamping and all that
stuff that a good Player wont do.......
So try to remember what of these thing could be the reason and ask the Admin
for Grace to play on the "Worlds most Favorite Servers" again .... lol
