I never got a response back. The mission I am making cannot wait, so the enemy machinegunners in my mission will be using default guns. If Marseille77 ever fixes his addon, I might go back and add the guns to the mission, but for now I won't be using his addon. If anybody knows of an addon that has heavy machine guns that I could add to the enemy machinegunners in my mission, please let me know or PM me. Thanks.
