Okay Button Disabled

Yes, I looked at the threads from people with a simmilar issue, their sillution does not work for me. Okay, I was in the middle of a game and I quit, and tried to go to a diffrent channel, when I did cf froze, at which point I had to force close it, now everytime I type in my username and password then click ok, the button does the animation, and then... NOTHING, I've tried reinstalling cf, it does not a help a bit.

Note: fullscreen mode, I've tried waiting, I just get disconected do to exceeded server wait time.
