How come the MicroSD2GB plays on my C-250,but not my Fuze 2GB?

  Could someone please explain how my MicroSD 2GB Expansion card plays on my C-250, but not my Fuze 2GB?  I thought they could be interchangeable. Is it because I loaded the MicroSD onto my C-250 using the Winamp Application,and not loaded it up onto the Fuze while connected to the Winamp?  Does this mean I need to by the Fuze’s Own Micro card?  Thank you.

The cards should be interchangeable but…what kind of files are you trying to play? .mp3, .wma, videos? 

Can you look at the card via Windows while it’s in the Fuze?
