Slitherine

I tried playing the game just now, I've been playing Stellaris for the past week or so but got disappointed with some of the features in the game. I still like the game but there are features in both this game and the other game that I wish both games could integrate. But in any case, thats not the point. when I tried playing the game just now, the intro menu with the play game button comes up, I press play and it takes me to a blank white screen and doesn't start. Is there a patch that I missed out on? I bought a slitherine version but redeemed the steam key and play via steam so shouldn't any patched be downloaded anyway?

on steam it's auto, apart from the beta ones
