So I was recently re-adjusting my keyboard bindings when my PC crashed. I rebooted, started the game, and everything worked up until the main menu screen. Nothing functions after that. I've uninstalled and reinstalled the game and the same thing happens. I verified the integrity of the files via steam and it checks out ok. In between all of this I had set my ROengine.ini file to Read only due to the 'Instance Rendering' not being saved to disabled. Changed it back, same thing, nothing functions beyond the main menu e.g. 'Exit Game' 'Play Online' etc etc. None of the options work. I have other games that work like Unreal Tournament 4, CS:GO works fine..
