My emerson mp3 player keeps saying "File System". It started doing this when the battery about died and I turned it off and changed it. I have songs on it but it says 00/00. I can't find the manule here at home OR online. It looks kind of like the BAR901, just not pink, it's black and silver and takes "AAA" batteries. There is no cable or software that came with it, it's a USB
