I have a sylvania 2 gb smpk2066 mp3 player. I tried to delete everything off of it. It says there is nothing on it, but it also says that there are only 1519 mb out of 2048 free. When I hook up the mp3 player to the computer it lists abunch of songs that are on the player. I can't get to them on the player and I can't erase them from the computer. I can't reload them onto the player because the computer says they are already on the player. How do I fix this problem?
