How to put a digital copy of a movie into iTunes?

Recently I bought Frozen on blu-ray, which came with a digital HD copy. When I tried to redeem it on iTunes, the Disney website told me I got the movie into my library. However, I had neither the movie in my iPod library, nor in my iTunes library on my computer (windows 7), and I had one dollar less in my iTunes account. When I tried to do it again, the Disney website told me I had already redeemed my code and that the movie was in my library. I have tried syncing my iPod and iTunes and I still have no movie on either. How do I actually get the movie into my iTunes account (and possibly my dollar back?)
