Connection Trouble

[Royann Greenwood]

Yesterday the game was running fine and today i opened it up and i get a red message at the top left saying Master Connection:This is taking a while...-Either your login is invalid or your firewall is blocking us.

Any ports i need to open for this to work?

Thanks!

You could be either BANNED, could be using a banned copy of the game, or it is what it says. Make sure ur login credentials are correct by opening the Project Cartographer launcher (not the Halo 2 exe). Make sure win firewall not acting like Nazi Germany and North Korea by blocking incoming and outgoing traffic.
