Run SFC:

Type "cmd" into the Search box above the Start Button>and when cmd comes up
at the top of the Start menu>right click cmd and click "run as Admin" and
when the cmd prompt comes up at the cmd prompt type

"sfc /scannow"

no quotes and let it run.

This may fix things quite a bit.

It replaces corrupt files with intact ones, if you’re not familiar with it.

If no help from SFC, you can try a restore point to before this happened or
you try the steps below if you have a Vista DVD:

I hope this is enough to get you on the right road for nºw.

Let us know how it works ºut.

Good luck
