Defraggler Crash / Close

Since I installed the latest version I have not been able to get a full defrag of any HD. Stops at about 50%, says error has occurred and must close.. Details reference a \locals~1\temp\c5a2_appcompat.txt file.

Uninstalled and went back to older version, same notice and crash occurred again..

Try running the disk checker tool available from the drive properties in Windows "Computer" (it may need to be scheduled on next reboot).

On rare occasions where Defraggler crashes this has fixed the problem for me.
