Care to clarify? What part won't work? Will the entire game just not load, or is it something with the multiplayer? It's kind of hard to help you or fix the game when all you say is that it doesn't work. It might be something with the system or browser you are using, google chrome usually works but other browsers have tended to not work. Also the internet you are using could prevent the multiplayer from working since some school or public internets prevent the multiplayer system from connecting properly. Hope this helps
