I doubt very much this is a registry problem. Let's try a few scans and see what pops up at us. It is very important that you follow these steps in order as I post them. After each scan please try your program and post results if it worked or not. If first scan fixs the problem do not proceed to next scan.
Go to
Start>>Run>>>type in Chkdsk /f
click enter...it will probably ask if you want to do this on the next reboot...click Y
If the window doesn't shutdown on its own then reboot the system manually. On reboot the system will start the chkdsk operation
When completed it will boot the system back into windows.
Let me know if this fixs the problem
Go to
Start>>Run>>>type in Chkdsk /r
click enter...it will probably ask if you want to do this on the next reboot...click Y
If the window doesn't shutdown on its own then reboot the system manually. On reboot the system will start the chkdsk operation
This one will take longer the chkdsk /f
Note... there are 5 stages...it may appear to hang at a certain percent for a hour or more or even back up and go over the same area...this is normal...
DO NOT SHUT YOUR COMPUTER DOWN WHILE CHKDSK IS RUNNING OR YOU CAN HAVE SEVERE PROBLEMS... this can take several hours to complete.
When completed it will boot the system back into windows.

Go Start>Run ("Start Search" in Vista), type in:
sfc /scannow
Click OK (hit Enter in Vista).
Have Windows CD/DVD handy.
If System File Checker (sfc) will find any errors, it may ask you for the CD/DVD.
If sfc won't find any errors in Windows XP, it'll simply quit, without any message.
In Vista you will receive the following message: "Windows resource protection did not find any integrity violations".
For Vista users ONLY: Navigate to C:\Windows\Logs\CBS folder. You'll see CBS.log file.
Usually, it's pretty big file, so upload it here:
http://www.flyupload.com/, and post download link.
If you don't have Windows CD....(this applies mostly to Windows XP, since Vista rarely requires use of its DVD while running "sfc")
Note This method will not necessarily work as well, as when using Windows CD, because not always ALL system files are backed up on your hard drive. Also, backed up files may be corrupted as well.
Go Start>Run, type in:
regedit
Click OK.
Navigate to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup
You will see various entries (Values) on the right hand side.
The one we want is called: SourcePath
It probably has an entry pointing to your CD-ROM drive,(usually D:) and that is why it is asking for the XP CD. All we need to do is change it to: C:
Now, double click the SourcePatch setting and a new box will pop up.
Change the drive letter from your CD drive to your root drive, usually C:
Close Registry Editor.
Now restart your computer and try sfc /scannow again!
