i just started to play this game recently. when i go to purchase a car, such as a bmw, the game crashes. i can purchase other cars without this happening. the game also crashes on certain tracks. while loading the track, it just freezes then shuts itself down again. on stadtplatz circuit the track disappears just as you come out of the first turn and does not reappear until around the last turn. how do you fix these problems? at first, i thought it was the disc, so i exchanged it for a new one, but it doesn’t help. i have no problems with forza 6. forza 7 is the only game where any kind of problems appear.
