Unfortunately the only way to get down to windows 8 is to do a factory reset of your system, which means losing everything currently on it. If that's what you're willing to do, I can walk you through it. If it's not, then keep trying to find a driver set that will load the game, if you can find drivers that will load the video at the beginning, then you are over the hard part, getting it to recognize the mouse/keyboard after is easy.
I wish they would fix this massive hole in their coding of the game already.
I have found a website for the requirements I guess I will see if it works.
