go to my computer when it is plugged up and delete the music from the harddrive of the player.

It doesnt sounds like your device is fixeable...most likely you will have to buy another player...the reason you need to buy a new player is because you are not going to be able to see the screen to do a manual reset....therefore no troubleshooting is available for you device...

change your usb settings to MSC, perform the delete, and change back.

do you have WMP10 installed? I couldn't transfer songs, although my computer recognised the player, until I installed it, I had an older version of WMP. and check in settings/power that it's set to auto power off on the player. the 'start updater browserDB' is normal after synching the player.
