When recharging my SanDisk c240 1.0 GB mp3 player, the screen locks up, and I cannot do anything with the player. I try turning it off with the power button, and nothing happens. No other buttons seem to unlock the device. Also, unplugging the device from the USB port does not unlock the screen.
Any Ideas on what should be done. I bought the player April 02, 2007, so the device is less than a year old.
