Goodmans GMP32000S-It's working(BUT)it's not ????

After connecting device, hard drive remains 'on' in device manager(XP) keeps scrolling up and down - device working correctly-device not working error code 42(not connected)
Unconnected & switched on it reads "no music files" understandable as I haven't managed to connect it yet, if I press Record- it tells me can't record disc is full !!!! full of what I cant connect!! Have uninstalled and installed driver-no different. wonder if it will work if I bounce it off the wall????
