I burned my cd's onto my hard drive with windows media player so I could back them up and convert them to mp's for my mp3 player. Now all of a sudden they won't play and media player is asking for a license. Deleting them and reburning them eliminates the problem but what's up with that? I don't want to have to reburn everything if I don't have to. And last thing I want is to have it happen again.
