Am currently having the same problem. I did exactly what you guys instructed and I still cant log on. Am at my wits end with this game. I got online once with no problem and now I cant this really stinks.
I have just started playing sins online. I have the latest patch but when I try to host a game no one can get in. I can join and play in other games hosted by another person though. I have been told by those who had similar problems that I will have to turn off all my PC's protection in order to host even though my fire wall allows the game. Please let me know what needs to be done to correct this problem
