Ok so im redeveloping cosford ab in the uk. To cut a long story short i already have some freeware that works in fsx. alfs uk airfields. its good but i was looking to change the frequencies as they are out of date. easy i thought open up the bgl then simply use the change frequencies button. not quite as when i open up the bgl only the runway appears and non of the other scenery such as the aprons appear as they do in fsx so when i replace the file back into my addon scenery folder, the rest of the scenery is gone. i have tried leaving the old bgl and the new one in there as well but only one loads, the one that has the lowest ;letter eg abcosford over afcosford so i have no scenery or no new frequencies. redesigning the airport wont work as for some reason when i put an apron into the design fsx freezes(program not responding) and windows closes it, so cant use fsx. does anybody know how to resolve this truly bezare problwm?
