Creating/editing AFCAD data FSX

I'm trying to edit, albeit minor editing, the default AFCAD airport information in FSX Steam.  I've downloaded ADE, the SDK (P3D 1.4), and have opened a stock airport.  I changed a couple things, however, FSX does not seem to read this BGL.  It's compiled and I've placed it in the Addon scenery folder but no dice.  I even moved it to Global scenery, but nothing.  FSX just ignores the change. 

I remember years ago editing default data in FS9 with ADE and creating new approaches, adding waypoints, ect.  I don't recall the method being much different.  I was able to close runways and everything.  FSX isn't allowing me to do that.

What am I missing?
