Did you try to reset it? Mine froze two times and it worked for me... or jus wait for the battery to die like it says, worked for me too.
1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
2. Press and hold the Menu and Select buttons until the Apple logo appears, about 6 to 10 seconds. You may need to repeat this step.
3. If the above steps did not work, try connecting iPod to a power adapter and plug the power adapter into an electrical outlet, or connect iPod to your computer. Make sure the computer is turned on and isn't set to go to sleep.
4. If this doesn't work, then you need to leave the ipod on until its battery is completey drained. Plug it in and when it charges enough go to #1. Repeat as needed
