You might want to include a little more detail other than " its not working" otherwise how could anyone possibly help you with the problem. When exactly does it crash? as soon as you load AC, when you click on the Online menu, once you have already hit the Star button ??? what other settings have you got set?, what are your computer specs. You cannot realistically expect anyone to diagnose a problem with " it just doesnt work" which is basically what you have provided..
