I am sure that this information is posted somewhere else in the forum and I should probably bump it instead of repeating it but I am out of time and already typing. Last night members were having problems getting the Co-op game to work, they could not receive invites or join a game. The question was raised which ports are required to be opened for this to work. The answer is:

Udp: 3074, 28960
Tcp: 28960

If you need help understanding how to do this with your router, drop me a PM, we will setup a time and go through your config. It is simple, should take 5 minutes and will make your gaming easier.

Thanks AstroDad, I will give it a try and see if I can host a game.

Thanks for the info!
