AI Traffic

I may have posted this question in the wrong forum, my apologies.I downloaded Dean Reimer's FA-18 Hornet Blue Angel with the goal of having the team appear at various NAS's around the world as AI traffic. The planes appear, they start up, taxi briefly, then somersault into the runway/taxiway and disappear. I am using MSFS2K2. What should I do to correct this problem?JC Martin
