it turns off about 5 seconds after playing a song everytime i turn it one. it powers back on 1 sec. later on its own. i was told it was because the music files were bad and i needed to erase all of it and sync it back on to the iriver i did that with my songs, they all have liscenses and it still had problems. does anyone else have this problem or know how to fix it?? please help
