I recently downloaded Microsoft Flight and have noticed that there is aload of add ons and previews for the game so the DLC planes, you haven't got, can be viewed and not look like triangles. But, when I visit the website to download them (http://marketplace.xbox.com/en-US/Product/Microsoft-Flight/66acd000-77fe-1000-9115-d8044d5308d2?noSplash=1) I try download them. I click confirm and then it comes up with a "Sorry" message.
Do I need to download them from another site? Or is this an issue on your side that you'll FIX?
