With Lion, Apple shipped iTunes 10.4. Now, I had iTunes 10.5 Beta 3 installed, because of the iOS5 Beta. After I upgraded to Lion, and started iTunes for the first time, I got this message: http://cdn.macrumors.com/vb/images/editor/attach.gif Translated: The file 'iTunes Library.itl' is unreadable, because it's created with a newer version of iTunes. Do you want to download iTunes now? So, anyone having experience with this message in Lion, and most important: what to do? Thanks!
