My Apple TV keeps telling me that I need to enable home sharing which I have done before. However when I try to do that it says that I need to enter my Apple ID and password. Now it won't recognize my password either. It gives me a message saying the password can't be found or that the password is incorrect. I know it is correct. But I actually went online and changed it just to get things up and running again. I STILL get the same message! Any suggestions?
