You're welcome, Steve. Do you know what values those registry keys
had before using the file? If so, you can change them back with
Regedit. If not, use System Restore to go back to a restore point
made before you ran the file. That will revert the registry (and the
rest of the system, except My Documents) to exactly where it was.
