Black screen when in game but visible when alt tab out

Hi,

I seem to have a problem with the game once it opens, I can the normal loading screen fine but once the game opens to play it goes black, when I move my mouse I can hear it all moving and selecting different options, the game is running because if i alt tab out for example then put my cursor over it I can see it as it should be but then when I click to play it it will go black again. Ill put some images in so you can understand it better. 

I have already tried reinstalling the game that did not solve it.
