Start screen flickering between start game, load game and geoscape

Alright, I start the game and for two seconds the start screen works fine, but then it flickers to black then geoscape then the start screen and I can't click on anything, I just bought this game, and I can't even play it, could someone tell me how to fix it?

btw I have the steam version and changing it to windowed and/or other resolutions did not help.

Oh shit sorry about the name, I didn't see the sticky about formatting, I have the most recent steam update.

Also requesting a change to the title so it can be in proper format.

So V18?
