After upgrading to firmware V01.02.31, newly sync'd playlists are empty

I was happily using my Fuze with MediaMonkey until I upgraded to the latest firmware V01.02.31 today.  Now when I sync my fuze, the playlists all show up empty.  The MP3 files are there and play properly, but not via the playlists.  Any ideas please?

Problem solved!

The instructions for the firmware install directed me to change the USB mode to MSC (Settings/System Settings/USB Mode). I had previously had that set to Auto Detect and so changed it to MSC. After I restored that setting to auto mode, the playlists now show up on the Fuze after MediaMonkey synchronization. I hope this can help someone else…
