Problems with computer player

I Have problems to make AI to create my modified units. How can I make the Computer player to recognize these units and how to make computer create them?

I am working on a 4 faces campaign map and i want to include more units. It works perfectly in one player game or multiplayer, but when a player is controlled for computer it does not work any way (the computer, i think, don't recongize these new units and don't create any of them). I am using a Melee configuration. The units are from the game (about 20) and others modified for me. So, my Question is: How can I make the player controlled by computer to recognize and create the new units in a melee tipe map? The orders for the campaign work well but without any of the new units. Please Help!
