Help me remove default buildings

Can someone show me the correct "Exclude" entry to remove the default buildings for San Juan Puerto Rico airport? (TJSJ). The freeware airport I downloaded is just perfect, but there were no instructions for how to remove the MS default airport, and all of my airplanes are parked right through many of these buildings. The terminal used by American airlines is basically blocked by the default building. Thanks for all of your help. Hernan ???
