Issues with Fuze+ and new Sandisk Class 4 32GB microSD card. WARNING!

I am having the exact same issue with mine.  new 32 gb card from amazon.com on new 8gb fuze+ player.  When connected to the computer, it sees the card fine.  I filled up the 8gb, then  I filled the sd card up about half full with music.  Then I disconnected it from the computer and it says that I must format the sd card to fat32.  I’m running win xp.  I formatted it and the problem persists.  Is the potential new firmware fix for this that the last poster referenced in the very near future?  I don’t know what to do here…  Should I return the card or fuze+ to Amazon, or both,…or should I wait?
