Well, I'd guess you're best chances are with them, particularly where it is possible to send them a detailed report from the game that will show them what is happening when it crashes, detailed info on your particular system configuration, etc.
I think you will hear from them soon. This being a weekend will delay things but I've had very good experience in a couple of contacts with them and getting a reply within roughly 24 or so hours.
So, I hope they are able to get you fixed up so you can go back to having fun soon. Sorry, I don't have any other suggestions beyond that obvious one to contact them.
