I figured this would be a good place to complain. I got iTunes 4.1 yesterday and installed it and everything, and for some reason it doesn't show any shared music. I'm connected to the school network, and my roomate did the exact same thing that I did and was able to access shared music. It just doesn't show the shared folder in itunes. Do you know if there's anything I can do to see the shared music?
You need to upgrade to the newest version of iTunes. Apple changed the way music sharing works, so unless you both are running the exact same version, you can't share.
