Maybe you daughter did something with it and made a mistake. Ask someone to get it fixed for you

I managed to get this sorted by changing the default setting in windows media player from ripping the CDs as a wma protected file to a mp3 file.

Sansa MP3 players will not play iTunes songs. Only iPods play iTune songs. Visit Limewire to download songs that you can play on your MP3 player.

My daughters done the same thing.You may need to reset the mp3 player. you can hold down the middle button and play button for a few minutes. this should work.

hard drive is buggered - try getting a adaptor and connect it to pc motherboard and run GRC spirite

My problem is that it will give me the option to register the Barbie Girls MP3 player, and it says "storing registration infortmation" but 3 hours later it has not changed! I dont know if it is actually doing something or if its frozen?!?!?
