Done, twice. Same error:

(same error with any other installed game)

I would recommend uninstalling and then reinstalling the game on your PC. I have provided the link below which walks you through doing that below for your convenience. It's possible that some of the game files were corrupted somehow which is why it is behaving
as if it is unavailable on your account. I am making the assumption that you are indeed logged into the correct account of course. Before you perform the reinstallation it might be worthwhile checking your order history in your Microsoft account to ensure
the order wasn't reversed or refunded for some reason which could also be a reason it is now unavailable. If you continue to have difficulty after you reinstall please let us know so we can continue to troubleshoot the problem for you.
