I tried connecting to the port on starka and on the domain, and I have connection failed for each attempt. This means that the port is closed, and that you can't connect to it. Sadly, I can't try using my CSS client since I am not at home. Finally, to be able to launch the game, you should had been able to run the executable, a thing you can't do from free accounts. I will notify the admins to take a look, but I suspect it's nothing.
