What does "need more sourses" mean? How come when I finally get a download I can't listen to them? They're corrupted! Only one person has downloaded from me. My husband has tons of music that I plan on putting into my "Share File", but if I can't download from anyone else, why would I put up so much for others? Is that what you have to do before you can download from anyone else? Sorry for sounding so dumb, but I really want to learn how to do this!
