Military AI Works

I have installed the gr4 and it was all working great but for some random reason the ai aircraft has disappeared from RAF marham but are still present at RAF Lossiemouth. Anyone have any suggestions?

My first suggestion would be to check that you haven't got any fs9 traffic files in your system. Quite often they won't knock out all your fsx traffic but will create blackholes.

Thanks Steve, that might be it as they only disappeared after I put the tucano's into Linton. I will give it a try.
