A friend of mine, who had the original game, installed the All-in-One swifter, and the T3AOnline.msi, and he could enter into the online without problems.
I installed in my computer the Online-Edition, removed the Gamespy address line and included the firewall lines with the port I used for the NAT portforwarding, and I CAN enter into online.
I can see my friend, and we can chat together. But after 1 minute of normal activity inside the T3A online server, my connection get lost.
I have tried it several times, and always the same. Always well, but after 1 minute, it appears a message:
Lost connection to Battle for middle earth II online, or something like that.
And it returns automatically to main menu. How can I fix it? Any ideas? Thank you very much!
