enigmaxg2: Seems like a .NET Framework issue
Try repairing the system excecuting this commands in order:
* Start > type "command prompt" > right click > run as administrator.
* Type in the command window: chkdsk C: /f /r
* It will say something about the drive being used and if you want to check it at next reboot, so press Y (Yes) and enter.
* Reboot your system, it will start checking for error in the disk/filesystem, it can take from 30 min to several hours, so wait patiently.
* When the scan/repair finishes, system will reboot itself and boot into Windows.
* Now repeat the command prompt thing: (Start > type "command prompt" > right click > run as administrator.)
* Now type this command: sfc /scannow
* Wait patiently while it completes, it can take from 30 mins to 1 hour, at the end, it will show you a description of what it found, reboot your system to complete repairs.
That should fix the issue, if not, try to rollback your system to an earlier state using System Restore utility.
that didnt work.
I only have 1 earlier stage, and it's after I had this problem, so it's no use.
