I doubt jEmplode had anything to do with it. It was just unfortunate timing; I plugged the empeg into one of those cell phone power bricks whose cord was apparently damaged earlier to try it, updated some playlists and tried to sync, lost, and then while it was rebuilding the database on player restart I happened to nudge the serial cable slightly (I have it consoled for some debug work) and it rebooted. Fiddling with the cable shows it's no good. Oh well, at least it was a sleazy adapter and not one of the nice, small ones.
