Not sure what you did but this should solve your problem?
1. Install Tuungle and restart computer.
2. Fire up tuungle (after making an account)
3. Join the AI War Fleet command room ( or any room really).
4. Click on the little rocket icon and select you AI war .exe
5. Make a game
6. Join & Have fun.
Haven't tried it with AI War though to be honest but with other games that's pretty much it. Hit me up if you want to try a game.
