It all started when I installed new drivers for graphic card two weeks ago, everything was kind a slower...so I adjusted some Video settings in game, and get things to work normal.
But yesterday some error showed up...http://img31.imageshack.us/img31/9589/errorc.png
It appears every time when I want to enter in: character sheets, warm up, match, online matches...
So I decided to renew my drivers, and reinstall the game...but I didn't work...then today I DLed new TE instalation, and installed, and it worked, but I was losing frames in online game, my player was moving weirdly, like sometimes just skip several frames, and shows up on the other place of the court.
Then again I decided to adjust some Video settings, and as soon as I changed something, error started to appear again.
Also when I copy Profiles from old installation to new one, I lose first 4 saved players...
Maybe its because of graphic card, but I can play other games without any problems (before and after new drivers), such as: Warcraft 3: TFT and NeverwinterNights...and some others on internet
