Hi, I have a similar (or maybe the exact same?) issue as what is being discussed here.. I have a brand new MacBook (OS X 10.5.4) <with wireless internet> and on it I have iTunes 7.7.1. Also in my house, I have another computer that has LimeWire 4.18.6 - it was just downloaded onto that computer today, and then several songs were downloaded into LW today, too. I just turned on my Mac and opened up the iTunes and a message popped up saying that my Mac was trying to communicate with the other "LimeWire Tunes." After a few minutes of trying to connect, a message popped up saying "The shared library "My LimeWire Tunes" is not compatible with this version of iTunes."
I guess I'm not sure what do to because 1) I had no idea that my iTunes on my Mac would be able to do something as cool as connect with LimeWire from another computer; and 2) Im working with two different computers. Any advice as to how I could get those songs from LW on the one computer to my iTunes on my Mac would be greatly appreciated!
