The OS X version of an online game I used to play has just been released. The game is called Graal Online. Anyways I download the installer, but when I click the icon it appear like it's openeing (the lines spread out, like in any other applciation) but nothing happens. I tried restarting the computer but that doesn't help. I am running the latest version of 12.02 and meet all the system requirnments. But the installer won't open. Any ideas?
