keep cool-headed
I would not open the mp4-player, because it's working. And dont try to "update" the firmware - thats very risky, 95% of them post in "dead player revival" after they have tried this!
Search to locate the problem at your PC: Maybee windows has forgotten the driver, reinstall the driver! Check the Windows System properties. Check if the USB Connector/Hub is ok and working. Install the driver on a friends PC and try if the player is recognised there.
