I'm having the same problem. With the mac version, clicking "new game" plays the initial flames animation then makes the screen go black (or in the newest version, makes the screen freeze on the main menu). I can click around and hear laughter and occasionally keys jingling and someone getting slapped. With Wine and the PC version, I am instead brought to an extremely dim image of something. I can still click around like before. In both cases, the game is completely unplayable.
