Just bought the game. Loads up in Windowed mode with black lines.

I picked up this game yesterday hoping I could give it a try, instead I was met with windowed version of the game which couldn't be maxismised - only minimised and closed. The game itself was just a thin line going across my screen and everything else was just black, I can also force myself in to full screen using ALT+Enter but it doesn't get rid of the issue. Does anyone have a fix for this? I have tried reinstalling.

Thanks.
