Call Apple at 1-800-MYAPPLE. (692-7753). They're very quick there. Just tell the first person you talk to (you know -- politely. Don't ruin his day and make him feel like a useless raisin lol) that multiple people in Apple Discussions are having the same problem and you think you're probably going to need a senior advisor because it's a complex issue with multiple possible causes. Or words to that effect.... That'll get them to move along quicker.
And never hang up before you get a case number bc if you need to call back, they'll never find your case (I know this bc as a broadcasting teacher, I had lots of Apple products and was often on the phone with them, especially at first).
