Be sure you are also using the desired KVQQ bgl. You probably have at least two. There will be a default one and then I expect your modded one. The latter would go either into a Addon Scenery/KVQQ Cecil (etc)/Scenery folder or an alternative location. Try to remember where you placed it. You want to in ADE "open airport" by "select bgl", browse to that folder and then make the changes described in this thread, save, and compile - be sure you browse again to the same folder location and, after backing up, overwrite. (If you are opening the "default airport" e.g., by filling in the blank line with the ICAO, KVQQ, you are likely using the wrong airport file.) You also need to conform the ATC_parking entries in your AI aircraft air.cfg accordingly.
Once you learn how to assign a/c to parking we're gonna getcha goin' on TrafficTools too!
