Crashing at Playground Games logo

I have never played a Forza game before and decided to download demo. I got it downloaded and started the game and as soon as it gets to the Playground Games logo it crashes and gives me no error or anything. What I do not get is all mt other games play perfect but a game made by windows will not even start. Well I am not buying this POS. if it will not even start. By the way there are a lot of people having starting problems would be nice to see some real support on here to help the people having problems. No way I am buying this in the current state it is in. Real game breaking when you can not even get the game to start. 28gig demo that does not work,what a waste of time.
