In your log image there, I'm not seeing that you actually dropped to a BASH prompt to delete the database and start over. It looks like you simply typed the deletion commands into the player's serial interface. When you pressed "Q" and Enter, it should have dropped you to a shell prompt (looks sort of like a DOS prompt) and it didn't.

Put developer beta 13 back on there, and make sure it really does drop you to a shell prompt before following the rest of these instructions.

Also remember that the major emplode version and the major player version must match in order for the synch to work. (i.e., it must be player 2.0-something and emplode 2.0-something).
