Pretty much as the title says. Up until earlier today I had no problem. I wouls download something from librivox, unzip it into my music folder and the files would appear when I opened the music player. No The only file I see in the music player is the samsung tune. I can play the mp3s if I open the file individually but as soon as it finishes it is gone from the player. I know I probably have done something amiss but have no idea what. Any help would be appreciated.
