I bought a full season of a TV show. I downloaded all episodes. When I go into my iTunes library, select the episodes I get a message of: This computer is already associated with an Apple ID. I can't for the life of me get the TV show to play.

I bought a full season of a TV show. I downloaded all episodes, I went to my iTunes library, selected the episode I wanted to watch. I got this message: This computer is already associated with an Apple ID. I can't for the life of me get the TV shows to play. I went on iTunes and when to my purchases. Clicked on the episodes and the same message popped up. How do I get these to play? I also see my download box with an error message saying it has paused the download. I click unpause and it just pauses again. I have been able to get one of the episodes to play once through, but now it gives me the same message.
