Damaged database - data.plist

Why do I keep getting this error message? I use a database successfully for awhile and then the next time I try to open it, it will give me this error message.

Sounds like there is a problem with your hard disk. The file is being damaged, so Panorama is detecting the damage and reporting the problem.

OR, this problem could occur if you are using both Panorama X 10.2 and 10.1. You should not do that. If you insist, then you must turn off database integrity checking in Panorama X 10.2.

If you have both Panorama X 10.2 and 10.1 installed on your computer, I recommend that you delete 10.1. You don’t want to ever use that again.
