I got an Aigo mp3 player for christmas and it has mostly worked fine. I put a few songs on at first thinking I'd add more later, but now later has arrived I find I am unable to add anything new to it. Currently it only has 670Mb of space used so has more than 1Gb spare. If I try to add new songs using windows media player it simply tells me an error has occurred, if I drag and drop from a music file I get "cannot copy ****, the directory or file cannot be created". I have tried deleting one file then adding a new one but the same occurs. Does anyone know if this is fixable? If so, how? I am loathed to try formatting the device as if I cannot add music, at least I have what's there now.
