Scenery Question?

I downloaded an airport scenery from San Andres airport Gustacvo Rojas Pinilla, The readme only stated to unzip Scenery\the files into Addon Scenery\Scenery subfolder; I added the extras gateways and morestatic objects from Rwy12 project together with JrM. And Ramp Lights. But it looks like this now:

I've contacted the author of the scenery asking how to delete it and go back to default, he replied that all I had to do was to delete the BGL's I've done that fromeverywhere I find them...Still the building remains???:isadizzy: How can I get rid of it? I have a working FSX\old copy on an external HD,That doesn't have the scenery included, could I just use that, and copy it over to my installtion??
Any advice is appreciated...
