Then unfortunately, your database was somehow wiped out by the companion when it disconnected in the middle of a transfer. This is one thing I did not fully test, and I'm sorry for that. The mobilesheetsbackup.db is created before the database is updated during the transfer, but it appears like somehow even the backup was wiped out (you didn't try connecting/making songs with the companion after the problem showed up, did you?). I really apologize for the frustration this undoubtedly will cause you. I am adding code today to try and prevent this from happening in the future by making the database automatically backed up. To make a manual backup, you can go to Utilities->Backup Library. If there is anything I can do to help, please let me know.
