Disconnect after every game

[KVIlN]

Yo, i have an error that annoys me since weeks

Every time i can join any game on any server, the ending of the game will make me disconnect and won't let me connect again on the server. It happens on every server that i play, and i downloaded the client this afternoon... so i don't know how to correct this.

Is there any cache that i can wipe or anything ?
Thanks a lot for helping me if you have any solution.
