When your picking your airport if the scenery is a aport click on search addon scenery other wise it could be faulty files
but it's every addon scenery file that get's put into FS9/Addon Scenery
Did you read the read me file?
Read me file for what, the scenery or the AFCAD?
both that tells how to use everything
yeah, it didn't say it would screw up my afcads anywhere, i was going to ask on the project ai forums, but it seems to be down for a few days.
do a sytem restore back to the date when fsworked without the scenery then upload it again
