iTunes movie rental download frozen

In the midst of downloading a rented movie from iTunes, it gave me a message saying it couldn't continue. I went to the downloads to pause and play, but it was frozen. i tried deleting them, but they were grayed out so I could select them.



I went to the downloads later and it said,"download error. tap to retry." it's frozen and i cannot tap to retry.



now what?
