Clip plays radio but not MP3's

Help! The radio works fine, when I try to play an MP3 song, the song shows on the display, the pause/play key works but when I hit the round center key I get diagonal lines across thte bottom. (I downloaded the fileware this morning).Plz advs…thanks!

It looks like the problem is with the player.  you are note supposed to get those line even if the songs you loaded are corrupted.  does it do the same with other files?  are those files playing fine on the computer?

I dont think anything is corrupted…should I try to download a new song entirely, and see if that works?

If the songs are playing fine on your computer, try reloading the firmware… if the same issue occur, call sandisk.  they may have to replace the player
