reinstalled os x and been trying to get my itunes set up. I'm changing the directory of my music and when i put in my old itunes data file into my itunes folder to get all my ratings etc then it can't find my tunes in the new folder...i have under prefs advanced...the new folder as the itunes folder....i figured it would work...i don't want to go through all my songs and relocate all of them...any tips?
