Mantis reports that my notes backup is successful, but when I go into the My Notes Editor I get the following:

"A critical error has occurred.
SQLite error near "s": syntax error"

And my notes don't appear.

Last time I saw this, I recovered by restoring the notes, lost most of them, and started over. I've got quite a lot of notes at this point, more than I'd care to lose. Any chance that SQLite error is a corrupted file or something and someone could rescue my notes?

This is the kind of thing that should be emailed to support so we can work with you individually and take a look at your notes file to see what's causing this.
