My husband and I both have Sansa fuze players.  When we first got them they were both 4mb.  My husbands died after a couple of years so I got him the same player, but an 8mb this time.  We both enjoy listenin to audiobooks and I have had a terrible time trying to get the downloaded books to play on the new player.  We keep getting messages like "Please obtain license by transferring this title to divice using audiobook software".  I downloaded the book through Overdrive Media.  I even tried updating the sansa drivers..that was a joke.  Needless to say, what is needed here?  What am I doing wrong or not doing right?  Will appreciate any assistance available.
