Ed,

What happens if you open a command prompt, type
defrag C:
and hit Enter?

Try running The System File Checker (sfc.exe).

Start | Run | Type or paste: sfc /scannow | Click OK

This will take a while.

If SFC.EXE did anything it will be in the Event Viewer.

Open the Event Viewer...
Start | Run | Type: eventvwr | Click OK |
Click System | Look at any Windows File Protection
entries

More info..
scannow sfc (sfc.exe)
http://www.updatexp.com/scannow-sfc.html

After running sfc, reregister dfrgui.dll and dfrgsnap.dll.

Start | Run | Type: regsvr32 dfrgui.dll | Click OK

Start | Run | Type: regsvr32 dfrgsnap.dll | Click OK

Hope this helps. Let us know.
