Nova to FSSC to AFCAD

The ten pound hammer finally drove it into my head how to use FSSC to put scenery onto an airport in FS9 
And I was able to make my first object with Nove, (Not sure if I like it yet).
The problem is my building appears stark white, I put textures on it with Nove and all appeared to be fine until I ran FS9 and the building was there just white.
Any Ideas what I didn't do, or did wrong?
I've Got Airport for Windows but haven't figured out how to use it yet.
