I had my Shuffle plugged into my Windows box the other night overnight, and when I woke up, I found that the computer no longer recognized it when I plugged it in. I tried plugging it into my Powerbook, and same story, it won't see it. The shuffle won't play anymore, and when I click "play" it blinks the green and orange lights on the front a few times. It will charge in the USB ports of the computers, but I just can't get it to play or get the computers to recognize it. Any suggestions? I've seen a thread on here where someone had similar problems, but they never got the issue resolved. Does anybody know how to fix this? Or is my shuffle a lost cause?
