Backup Image Corrupt

Using Comodo Backup 4.0.7. I have a 5GB backup in the CBU format. Comodo gives an error saying Image Corrupt. I’m unable to mount it. Is there anyway to salvage the files?

Any help would be appreciated. Not sure if the backup is really corrupt or if Comodo Backup isn’t all that reliable.

Fixed the problem by downloading a replacement CBU.exe from this thread here:

I can die happy now!
