Hello there, Thanks for using Justanswer.
I am Nimman and I will be assisting you.
Are you on the same computer now ?
Reboot the computer, and keep tapping the F8 key immediately when the computer starts, and before you see the Windows Logo. You will see a black recovery console. Select Safe Mode from the menu using the up/down keys .
After you log in to Safemode:Click Start, and go to Programs>Accessories>System ToolsClick System Restore and chose a date when the system did not give the user profile error.
Let me know the result.
