I am running the latest version of iTunes and OSX. Everything was fine until then.

I went to purchase a movie from within iTunes and as soon as I hit Buy, iTunes locked up and would no longer respond. I thought it was a fluke, and went on and purchased on my AppleTV (3, latest software) and was able to watch the movie. However, iTunes on my Mac does not show the movie as being purchased, even though my Apple TV, iPad and iPhone all show the movie as purchased. When I go into iTunes on the Mac, and select Store menu, Check For Available Downloads, nothing comes up to download.
I have deauthorized and authorized.
I have checked/repaired permissions.
