i just copied my itunes library from my imac (snow lep) to my new mini(lion). when i went to launch itunes i got a message stating that "itunes librar.itl cannot be read because it was created by a newer version of itunes". true, but here's the thing- when i try to update, it says that i am already up to date. this is not true though because the mini is running itunes 10.5.3, and my imac's itunes is on v 10.6.3. what gives?
