How do I call JSON from the Kongregate API with Unity?

I am using the WWW class to get JSON back from the Kongregate API.

I keep getting the dreaded ‘No valid crossdomain policy available to allow access’ error, and since I can’t put my own crossdomain.xml policy file on Kong’s servers, how the heck do I call JSON on the KONG API?

Any advice is appreciated.

Thanks
