Content not authorized error message
I am trying to watch a movie rented on iTunes. When I try to watch a downloaded movie I get an error message that says content not authorized and can not watch the movie. I did some research on line and some people say it is because I have too many devices in my account. Strange. It okay. I remove so I only have 4 devices. Still won’t play. Any ideas.
