hey i got limewire and itunes for my ipod. i do not want to pay for music so limewire is my source. music is my life. i tell limewire to play the song from itunes instead of limewire for my ipod. i have had limewire for about 2 years now. this is the first time the following problem has occured. when i click on an mp3 file itunes does not do anything. it just sits their. but if i play an m4a file it plays on itunes fine. please help.
