Its happening to me since the last actualization to 0.45 stable. And since I just entered a server, and at 3 minutes, all the people from there was banned with no reason, including me.
Since that, I have conection problems, and the game crashes.
I´ve tried to verify the integrity of the game cache (propeties>local files>verify integrity of the game cache), but I can´t, a window appears and says "You have to close every game or tool that´s running before verify.
Help please!!
