How come when I hit the rebuild scenery database and everything seems to go fine and I start up fsx and there are no concourses or terminal buildings. Runways and taxiways are fine it's just the buildings.Thanks.

it wouldn't be rc that made everything disappear. sounds like a fsx/fs9 option, particularyly the video/visual setting has been changed. happens to me every once and a while when i'm trying to improve frame rates. you just have to remember what you last changed, and undo the changejd
