Thank you very much for reading this. I will be as concise as possible. I upgraded to Leopard two nights ago. The upgrade was successful. However, Leopard lost (for lack of a better word) the one and only "user" I used pre-Leopard. Yesterday, I spent 92 minutes on the phone with Apple support and 45 minutes with an in-store Genius trying to fix everything. I am still having a host of issues which - to my novice eye - seem to relate to "permission" issues. But the purpose of this post is narrower than that... I have spent about six months carefully rating approximately 3,500. Now, the ratings are gone. Can anyone teach me, in layman's language, EXACTLY where ratings are located, what the folder(s) is titled, and anything I can do to "teach" iTunes where the ratings are. (Screen shots are very, very welcome and appreciated.) Ratings are very important to me, and I don't want to lose the work I've already done. I can't thank you enough in advance if you can help me.
