I recently changed pc's. I downloaded iTunes to my new pc. All my music was there. I have a different e-mail address and password. I try to play the music in my iTunes library; but, iTunes won't let me. It asks for my name and password. I give them my new one and my old one and it won't accept either one. So I can't play my library music. Would you tell me what to do? Thanks, A. Paul Fotheringham (old e-mail address: wyomingcowboys@sbcglobal.net
