I've lost all my nice MS default "high quality" airports in FS2004. I just have flat land where they used to stand - San Francisco, Sydney etc, all gone

To explain what happened...
It's my fault they're gone - I installed Golden Wings over my normal FS9 because I couldn't make my GW FS9 version work.... this was before Silver Wings...
Now my GW version suddenly works and I've uninstalled GW textures, somehow, but the airports and seemingly much of whole cities are missing...
Does anyone know where these files 'live'? I've tried reinstalling, eg. San Francisco, from the disc, but the airport still isn't there....
Any help for this Sorry Fool much appreciated

Regards
Krigl
