Game randomly crashes, at any time.

Only got the game today, and I've tried 4 times to start a new career with a custom team. The first time the game cashed whilst browsing the rider schedule, followed by 3 more crashes whilst cre-ating my team. I tried a 5th time using an existing team, and managed a whole 4 days in the game before that too crashed. Any ideas how to fix?
