Q: My downloaded TV shows from iCloud library won't play.  I just get a black screen.  Please help!

Hello momofoto

One of the main things to start is to make sure that iTunes and your computer is up to date. If all is good there and still having issues, then try and delete the TV show and then download your purchase again from the iTunes Store. Check out the article below to go through those steps.
