The old version of Microsoft Flight, that I spent like $100 on additional content for, stopped working because it relied on "Games for Windows Live" servers that Microsoft no longer runs. I spent about 5+ hours on different support calls trying to figure out a workaround, but to no avail.
The sad truth is that any company that uses DRM couldn't care less about you. They only care about money and they won't even push an update to remove DRM for a game they don't even sell anymore, so that people who paid money for the content can actually use said content.
