There is problem, And I don`t know why-when i login in multi player in one point it just stuns-its running (in task manager) but i have no control what so ever. and wen i close it and open again it doesn`t open... After some time I manage to log in and same problem... It hapens every time at random palec of multiplayer-game, weapons, skills... There wasn`t such problem before-it started this yesterday...?
Can somebody help???

Haven't seen this reported. Sounds like something new software-wise happened to your machine. New device driver? New background task, port checker, or updater? New USB device?

If you always just sleep your machine overnight (like I do), reboot. Load task manager (with C2 in windowed mode) , sort processes by CPU time and see if anything is grabbing all your clock cycles when it "stuns"....
