Apple ID email already in Use
When I try to set up a new apple ID, it asked for a non-apple domain email account. When I try to use my email address, it says it's already assocaited with another account. My email address is very unique and I doubt anyone else knows to use it. When I try to search for it using look up apple ID, it can't find any apple ID associated with that email. So I'm stuck...why does it say its in use, but when I search for it, it can't find it?
