Hi, so sorry about that.
May I ask you when did the crash occur? Did it say anything about the crash? Did it automatically close the game or was it just Not Responding? If it's just about Not Responding then please be patient, the game takes time to pre-caching data so that you'll have the smoothest experience possible. If it said it had "crashed", please follow the instruction how to report a crash.
One more thing, could you provide your PC specs? I've tried to support the lowest PC specs possible, but limit is still limit. Thus, older computer rig might not be able to run the game, as the game require a Core i3 Sandy Bridge for Mobile or better.
