I just purchased and I've copied photos to the SD card but I cannot figure out how to place music onto the card so it works with the frame.  I tried using "SYNC" from Vista to copy the music onto the SD card and I've played the music off the SD card on my computer; however, when I try music on the Polaroid frame, it says there's no music.  Any idea how I can get the music onto the SD so the frame recognizes it.  I can see from the frame when I select "file" that the file folder is there but when I select the folder, it says "empty".  I'm downright surprised that Polaroid put out the product without a manual to describe how to do things.  Help!!!!
