Freezing and stucking

HI!
When I try to connect server, choose channel, room or when I end game, leave black market, try to start game I get freez and game stuck. In process menager it still works, and use processor but I cannot do anything in menu or game.
I reinstalled game few times, added ports exceptions in windows firewall, router and comodo firewall and I added Cf files to trusted zone.
It didnt help.
I downloade Gamebooster and tryied to start Cf by gamebox (I disabled all services I could and use virtual desktop) not works.
Can someone tall me what to try now?

By freezing I mean game stuck, I can move mouse but when I click on some menu buttons it show loading all buttons are disabled and game stuck, could w8 hours and it still will be freezed. I have to close it by menager and start again.
