Ahh help! Okay, so I was putting some Fergie songs on my Sansa c140 and all of a sudden it kept saying one error and wouldn't put the songs on, so I unhooked it and hooked it back in, it kept doing it, so I went to see if the songs were on there and it just wasn't showing up, it wouldn't let me see the songs, and it kept freezing when I would try selecting one of the options for the songs, I can only listen to the radio and I have tried formatting it, I have tried hooking it to the computer but it doesn't show up. But the CD I was putting on it skipped....would that have anything to do with it? Please help! I have had it since Christmas and I can't take it back because my mom got it off ebay....Please help! Oh, and also, it said I had over 400 MB left on it, but when I turn it on after the Sansa screen comes up, another screen comes up and it says, No room for DB(which i'm guessing is Data Base) please delete 4.0 MB...but I can't..because it won't because it won't show up when I put it in the computer. =/ Help!!!
