I had the same problem as you before. I always failed to log in, so I can connect the internet cable again, but I can't do it next time. Later, I found the right-click property of your broadband connection like this, and then I clicked Advanced and then Settings, and talked about the firewall settings page exception, and then I clicked Add Program, and then I decided to add the same city game. That's how I got it. Hehe, I don't know if it helped you.
