Is the game running at all and crashing while playing or is it just crashing as soon as you run it? Have you run Impulse and made sure you have all the updates? Have you made sure that you don't have any incompatible maps or mods loading?
If none of this helps, you can contact the official support at email@example.com
At least I think that's the right address. Annatar or someone else should respond if it's not and possibly with more helpful advice. Good luck.
