[arniepie]

first time post!!!

I am a long time MSFS-user and made many AFCAD-files before,now I ran into a problem.
I have changed (2+parking spaces) the AFCAD bgl that came with addon scenery from FSIA (seychelles int.).
Now every time I try to load a flightplan Immediately after I select FSIA+parking-place I get a CTD.
I ran fault finder in AFCAD for FSIA and no faults.
All other airports (as far as I can see) seem to be unaffected, anyone else experienced the same and found a solution for it?
I would really like to use my new layout.
All help is greatly appreciated.

Some have reported problems with having duplicate AFCAD's in the same folder. Do a search on your airport, and see if more than one shows up. It may also help to run the fault finder on the airport you edited.
