It won’t even launch

Sorry, I’ve played this game before and it was great, scared the hell out of me. But this 20$ version won’t even launch, it offers to open it windowed or full screen and with either button I press my screen just flashs black and its goes back to my desktop. I have uninstalled it and re-installed it and it’s still the same. If they fix it ill change the rating but until then I’m giving this 1 star.
