When selecting certain songs that are loaded, there are times that a song will get stuck and I cannot advance to the next without removing the battery. Even with that done, it still happens again. The songs are all in .mp3 format and they all play fine in windows media player. What can I do to clear this problem so that I can play all the songs in the player without any of them getting stuck? Please get back to me asap @ jledee0405@yahoo.com and/or (904) 697-6142. Thanks... Jeff Ledee...
