Ok I tried the game and it is indeed trying to use a non-standard port (1626 by default). Here is how to forward ports:
- Start > run and type "ipconfig"
- Note down the IP address and default gateway.
- Open IE or Firefox and enter the default gateway as the address.
- It will ask you for username and password. Usually "admin/admin" or "admin/password". If not, Google for your router to find default admin username and password.
- Go to <a href="http://www.portforward.com">portforward.com</a> and (follow static IP guide if you haven't already got one) find your router on the routers page.
- You can pretty much follow instructions for any application guide there, just replace names (Shockwave) and ports (1626) where appropriate.
