hi i'm paula. jus need some help please. got limewire and when the mp3 file says it's finished downloading, i go to my saved files on limewire folder. when i send it to my music and load it in windows media player, it says "the file u are attempting to play has an extension (mp3) that does not match the file format. playing the file may result in unexpected behaviour". this is so frustrating cos i get no problems usually. what am i doin wrong????????
