I have been using this app for a few years now with no trouble using it until today. My galaxy S3 required a factory reset so I made a backup to my pc. When I moved it back and subsequently tried to login to my old database  the app tells me Invalid Password. *UPDATE* I resolved it by uploading my backed up database from my pc to my dropbox  fresh installed UPM  told UPM to sync database from my dropbox. Somehow that was different than dragging the database from my pc to phone  but hopefully this helps someone. Score changed back to 5 Stars.
