I've played successfully months ago, but went back to play again today and when I go into single player game, it claims I need to purchase the base game. I already have it installed via Steam. I've uninstalled, reinstalled, ran the local file fix on both steam and stardock. It does claim constantly that there is one file it keeps trying to 'reacquire' but doesn't tell me which one it is or where it is or even that it's failed to do so.
