Cannot connect to server, server may be down

You are probably behind a firewall, which is configured in a way that prevents the game to connect to the game server. If that is the case, you have to do one of the followings in order to play the game:

• configure your firewall to enable port 4989, or ask your system administrator to do that,
• play from another machine, which is in a less restricted environment,
• try practice mode (billiards only), this mode is available from behind a firewall as well.

You might also need to clear your cache after.
