Just a quick thought here Mike.
When you got the AI aircraft lined up on the runway and ready to go, did you go to the top of the screen, hit the drop down menu and tell the AI aircraft to start their run ??
I installed it the other day and it worked straight away, but even though the AI were on the runway with engines running I still had to start their run up from the drop down menu at the top of the screen.
So remember, use the drop down menu first for the AI to show up, and once again to get the AI to start their run.
Hope this might be of help to you.
