All of the music (each song) that I had on my computer before loading Limewire is now listed in Windows Media Player Library twice after having used Limewire. Any ideas as to why and how I might correct it without just deleting each duplication individually. Thanks

If you have doubles make sure all your music is stored in one folder on your desk top. Its not a good idea to load the music from Limewire, best to move the songs to one location on your drive and make sure you dont save the files as a playlist but in MP3 format.
