I'm trying to set up home sharing within iTunes on my MPB so that I can control iTunes fom my iPhone. When I go to the Home Sharing setup screen, enter my Apple ID, and password, I just keep getting an error saying "Home Sharing could not be activated because the account or password was incorrect" Thing is, the Apple ID and password that I'm using are the exact same details that are configured for my iTunes account - i.e. all of my music, apps etc are purchased with the same details. I'm entering the details correctly also. Double checked password etc. Is there anything else I can try?
