This movie cannot be played on this machine
I recently bought Hamlet from itunes. It's a 4 hour long movie (taking an English class), so it took a loooong time to download. This morning I started watching it, but then I put my laptop to sleep, and it later shut itself down due to running out of battery power. Now every time I try to play it, it gives me the error message "This movie cannot be played on this machine". I've authorized my computer to play downloads, so that shouldn't be the problem. Can someone help me out with this, and if this movie is indeed unplayable, is there a way I can be refunded for my purchase?
