I installed the preview from Xbox App and I tried via the launcher and when I ran the game, it came up with a Windows Pop-up about me not having the license for it on the account. Please fix this. Thanks.

By the way, it must be to do with the fact that the preview is trying to check for a license that doesn't even exist. We're not actually ever given a license when we buy the game because the game is intended to allow multiple free accounts if one of them owns the game. So, something went wrong in the code but I'm not sure what.
