After looking over extensively your computers situation I have found that one or more of your
Windows Files have become corrupted or deleted. To combat this issue we are going to run the System File Checker on your system which is a built in Windows checking utility that checks and fixes corrupted Windows Files. Please follow these steps as best as possible and if you have an issue please post it back in your next reply:
Windows Vista Method
Please read these steps
CAREFULLY as these steps are much harder then the Windows XP method:
- Click on the Vista Start Globe

- In the Search Bar type in " cmd"
- Right click the cmd search result and choose Run as Administrator
- In the Command Prompt type in " sfc /scannow"
Please reply back if this program repaired any files, or if you had any issues reply back with what the error was in your next post.
