All my account information in this apps was removed and I can't log in again. I restore the computer before update but it didn't solved my problem. I reinstall these applications but nothing happened problems still remains. Please help ! I don't want to restore my computer to factory setting. Update: I solved problems with ATI Catalyst removing it from AppData but other problems still remains.

Hi, First, you should post your special error code at here. Secondly, I suggest you go to ATI official website and get the latest driver from them. Use that one and see what happens. Finally, you shuold try clean boot mode.
