Account sign-in failed on Apple TV
Using Apple TV (3 generation) to sream a video from iView(ABC TV) going for 20 minutes perfectly then it stopped steamming through my iPad2. Apple TV then switched to downoad Music on Apple TV but it went on continously, so I closed it down. I went back to iTunes 11.0.1 and tried to sync iTunes with Apple TV but it went on continously also. So I had to force quit iTunes to stop it looking for Apple TV. I then went back to Apple TV and under 'Computers' tried to connect to iTunes but to have the Apple TV app ask me to change my password as it could not find iTunes. Now after disconnecting Apple TV at the set and re-connecting, it kept saying-'Account sign-in Failed' and I cannot now connect with iTunes at all. This seems to have happened since I upgraded to the latest version of iTunes software. The Remote App also cannot syc with Apple TV now. I have nowhere to go now and I can't use my Apple TV. Please advise what I must do to sync with Apple TV on my HD TV set.
