AFCAD 2.21 & FSSC 1.5.11

Ok I am really confussed, I've built an airport with AFCAD for FS9. Now I would like to enclude some buildings support facilities. I have FSSC as well and it works great in FS2k2, however I can not get it to see any files in FS9.
I know that on the web for FSSC it says it supports all versions of FS up to FS2k2.
However I keep reading on the forums responses to questions about adding scenery to FS9, to use FSSC. So my Question is how do I get FSSC to load the airport that I created with AFCAD so I can add the buildings and all to it?
My duel runway airport with all the AI traffic on it sure looks bair without any scenery
