having trouble with mp3 player

ok here is the run down. i have a sandisk sansa e260 v2 and i just bought a 4 gig micro sd card for it. But every time i try to use the sd card on the mp3 player it freezes about 1/4 of the way from done please help me nerds!

Freezes 1/4 way from done of what?
Formatting the card?
Adding music?

refreshing the database

I’d format the card…is there an option to do so in the Mp3 player? If not format it via computer

fixed
