It says "limited functionality" and that dev needs to come into compliance. Game will not start up at all.

This game simply will not load. It crashes on startup every time. I have an i7 4790k, gtx 1080. Windows 10 fully updated.

Am i living in the twilight zone? This is such a great casual party game.

Bought the game a couple weeks ago on sale--and haven't been able to play it yet. You get the game sounds and a black screen. And then I see discussion from over a year ago and see that was the case back then too. So is this something that was never fixed?...

...that's it, really.
