at one point in time, i was successfully able to transfer and listen music on my curve.
i recently upgraded to a 4gb card, transferred all of my old pics/music/video to the new card.....all worked fine, as it did on the 2gb card.
NOW, when i try and transfer music to the new card......it'll transfer fine, but when i try and play it...i get an "not supported" error message. when transferring, i tried it both "convert for optimal ..." AND "no conversion"....neither worked!
my music on my pc is mpeg3, from my ipod. these were ALL mp3's at one point, then i suppose they were converted to mpeg3 by iTunes.
