Like many others, I am getting a connection to server lost when I try to play the game. I start my own game with AI bots, my commander lands and as soon as I try to build something, I get the connection to server lost, returning to main menu. I just want to play with AI in sandbox mode to get a feel for the game. I have McAfee antivirus and have tried turning off the firewall and turning off real time scanning with no luck. Do I need to forward any ports or change any other firewall/antivirus settings?
