Use default maps that come with the game. They are small enough for 1on1. Or modify them in FMB. It is easy and will be more useful for you.
You have birthplaces set in your mission:
Code:
[BirthPlace]
Blue_Fighters 2 12278 10561 0 12 1 0 . . .
Blue_Bombers 2 18693 9941 0 12 1 0 . . .
Red_Bombers 1 18062 30725 0 12 1 0 . . .
Red_Fighters 1 13896 30863 0 12 1 0 . . .
So when you create server and start mission you should have army selection in the top left corner. If you don't attach the screenshots as this would be very strange. And remove AI completely from your mission for starters.
