@markiemark, I dont know if this helps but I hadn't used mine in a while and when I plugged it in it got this error. While plugged in and the error showing I pressed and held the power button and it turned off. Then while still plugged in I pressed the power button again and it started up with the demo. If that doesn't work I may have also been pressing the other button while trying to turn off.
