First of all, no preaching about backing up. I back up to the SD every night and sync with my PC about ten times a day.

The problem is that I had deleted (all) my memos to fix another problem, and never reverted back to restore the memo database thereafter. Subsequently, since I don't write or read my "notes" on a regular basis, I didn't realize that I had been backing up and syncing to an empty file. So, even restoring from my back up from 5 days ago won't help.

I'm sure that the old file is somewhere on my PC. I just can't seem to figure out where it is or how to do it.

Any help would be appreciated.

Obviously, when you have done multiple synchs or multiple backups, you have erased your previous data.

If you back up your PC (as you should), you may have an archival data of your data from a week ago.

Good habit to do grandfather, father, son, backups for this very reason.
