MTP mode has stopped working with Sansa Fuze 4GB

My sansa Fuze doesn’t work with MTP mode anymore.  The problem started when I accidently left it playing music overnight and its battery ran out.  Nothing on my computer recognizes it anymore.  MSC mode works, but I was really enjoying having Windows Media player do everything for me (playlists and album art don’t sync).  What can I do to get my Fuze MTP compatible again?

(I use Windows XP)
