forza 7 wont load. freezing on splash screen

i purchased forza 7 2 days ago from the windows store and have played hours of it with no problems at all. I have been trying to play it today but it just freezes on the title screen after i presss Enter to play. the little wheel is still spinning but nothin else is loading. i have opened the game from the store and rhe desktop shortcut but its just the same. i have also closed and re tried many times now. anybody else having issues?
