Cannot play purchased movie on Apple TV

Having issues watching one particular show that I purchased recently on Apple TV 3rd generation. I have watched it a number of times, but then a week ago i keep getting this message whenever I try to play it, "iTunes currently unavailable please try again later". All other purchases work fine and I'm able to connect and watch them fine. However, whenever I choose to watch that particular show it gives me that message. I've tried updating to latest version and resetting everything. Not sure what's going on. Suggestions?
