The battery is not replaceable. I would not try opening the Fuze up as this would void the warranty. Try the steps recommended above my post and if all else fail, contact SanDisk for warranty.
Edit: added below info:
Make sure the files are supported by the Sansa. It may show when opened using a computer, but if it is not a supported file type, the device won’t display it.
