Corrupt Registry?

[wildpig]

I have been using Sprite Backup without problem up til recently. My last successful backup with no problem was in Aug. I also experienced the recent GPS crashing problem which a lot of people gone through. The GPS problem is solved but now whenever i try to use sprite to backup my phone it would go thr the motion but in the end it says back up with error:
"Failed backing up system setting"
I checked around internet and it turned out that you can force back up by unchecking the "check for corrupt registry". But that would mean the backup may have problem.

Anyone else has this problem with sprite back up? also anything i can do to check/fix this possible corrupt registry? thnx
