On my mp3 player, i have many playlist (.pla) and they work when i listen them to my mp3 player, but not on my PC, i can't open the playlist (.pla) and change or add more music. I can't add new playlist too. The option isn't valid now like before.
All of my playlists are already here, them appear but i can't open it. Windows didn't reconnized them and they are no solution for open them.
But if i open my mp3 on an other computer (laptop), i can see the playlist .pla, and i can modified them. but not on my PC.
so i think it's a problem again with the drivers or i don't know what.
