I got some AI flightplans, and they had KPNS in them. I told AFCAD2 to compile, and I got a message saying that KPNS isn't in the Aiports file. I started flightsim & it WAS there! but it is NOT in the Airports030528.txt file. Why is this?

Have no idea why, usually there is some sort of text file in the included with the flightplans with airports used (like MRAI's)Anyway, I happend to have it in my airport.txt file from somewhere so here it is:KPNS,N30* 27.64',W87* 11.13',121.
