PhotoStructure uses a bunch of techniques to keep your library intact and valid, but unfortunately, power outages, software bugs, disk errors, and network errors can all take a toll on the integrity of a library.
PhotoStructure runs some validation on library databases on startup, and if those fail, it will ask you to try to recover from a library database backup.
If none of the backups work, you can restart your library from scratch, simply by deleting the
.photostructure directory that you find in your PhotoStructure library.

Know that you’ll have to wait for PhotoStructure to rebuild your entire library, so this may take a while (even days, for very large libraries!)
