Hey, you need an adaptor for your computer to charge and update your MP4 with the latest programs. Or maybe an error is running with the cirucuitry and it has a small glitch with your screen. Either way if it doesn't work after this you should see a technician or a specialist in iPods. Also you may get it replaced if you have a warranty on your MP4 from whichever shop you bought it from, if from someone else ask them for the receipt and the shop. If no help then I reccomend to buy another one because your emblem in your screen is messed up. No problem :)
