Contact the people that sold you the movie and ask for your money back.
Is this the movie you were downloading? What do they charge for then download? It is a recent flick and I hunk it would be very costly.
Instead of a download, you could buy it and have it shipped to you in a couple of days.
Wait, I forgot to ask where you live. Here in the USA that movies is not ready for streaming or download. In what country do they let you download it?
