Issue with Win7 Pro MP12

MP12 STOPPED working recently due to mf.dll issues
Trying to fix it manually caused it to quit working totally and take me to an error page stating something was wrong with my audio (Which it wasn't)

So now I'm stuck TRYING to get it working again...is there anything I can do Short of reinstalling Windows 7 Pro to fix it?

Run an sfc /scannow to repair system files.

If that doesnt solve the problem, do a repair install.
