I had set the screen lock on my zune to ensure that it did not play when it's in my purse. The other day I was entering the code and must of clicked "ok" too many times and it locked up. I cannot put the code in now.. therefore I cannot do anything with it. The play/pause button will work and the back button will work as well. I cannot restart it either do to the whole center button not working at all. The battery finally died and I plugged it in to charge, the code screen came up again and I thought it was going to work because it let me move the numbers up and down. Once I pushed the center "ok" button it stopped working again. Is there anything I can do to save it?
