Dragon Age Inquisition doesn't start?

been looking forward to this game like no other. Months of torture anticipating it... I could barely even get through the day waiting for the release tonight. When I try to run it, a black screen pops up and less than 10 seconds later the game crashes and exits. I pre-ordered watch dogs and I've never felt so let down in my life. On the verge of a stroke right now. Hopefully this gets fixed by the weekend.
