After detaching the USB connecter from the player it started the “Refreshing Your Media” stage and has now been frozen there. I cannot turn the power off to reboot, does anyone have any suggestions?
Keep holding the power button down. It will turn off eventually.
You’ll want to remove and check out whatever you just put on it though to cause this, or it will happen again next time you turn it on. It’s ususally caused by an ID3 tag issue.
