I'm only guessing here @raymond+clark but- is it a premiere rental ? and are you watching on a screen that isn't connected with an HDMI cable ?
if so - I think this is something we have heard of on the forums where the extra copy protection on Premiere rentals is too much for Scart / magic eyes to cope with.
in which case - ask the Skystore team for a refund.

if it's not the above - a good first step is to delete the download. Then go to the deleted items and delete again.
then download it again.
