I had just finished installing the game on my Surface Pro. I was running it in windowed mode (default) and decided to try fullscreen. After alt+tabbing out and trying to bring up the virtual keyboard to take a screenshot and then alt+tabbing back in, the game crashed on a DX error. I tried again and again and the game would consistently crash upon fullscreen initialisation.

A reboot later and now I am getting this error.

Also, is there any way change to windowed mode without booting the game? Thanks.
