I am not able to get into the game with IE9. Firefox works fine, but with IE9 I always get: "Card Hunter is currently down for maintenance. Please try again in a few minutes." I deleted my cache and am not sure what to try further.
I've had that issue when I'm behind a firewall, like at a place that offers internet access. I believe you need port 8080, and you can check to see if it's blocked here:http://www.yougetsignal.com/tools/open-ports/
