If you are connecting to PC via USB connection and display of player simply shows player and PC with zzzzzzz in between, then you may have the same problem i had.

I spent a week fiddling with my player i was getting very intermittent connectivity to various PCs. Then finally it stopped connecting to any PC and not even charging at all from it's charger. It was so frustrating but last weekend I tested with a different USB cable and this resolved all my issues. Today it connects instantly. When connected to PC, player display should show player and PC with an arrow between them and no zzzzzzz. In win xp you should then find a new removable drive in the explorer window.

If you notice that the usb cable slides in without any effort and does not secure properly into the mp4 player port but there is a lot of sideways movement, try replacing it, the new cable I got fits securely in place and needs some pressure to plug into the player port.
