This will be one of the many (thousands of) cheap and effectively unbranded MP3 players made using SigmaTel chips and firmware.
Google SigmaTel and you'll find similar stories everywhere -- and SigmaTel, though presumably they know of the problems and could offer firmware fixes, choose not to.
Rather than waste time -- just bin the thing and swear never to buy unbranded stuff.
I was given a "Classic" MP6410 player made by Combined Luck Industires. My computer recognizes the player (as a STMP 3400 chipset), but cannot find the software to load it. It does not show up a drive or a removable storage device. When I try to call the manufacturer, I get a satellite network service provider.
Can someone point in the right direction to make my computer recognize this player? BTW, this is the first mp3 player I have ever owned.
