As GSX can choose the wrong AFCAD when scenery is installed into the documents-folder, I moved my scenery into the P3Dv4 folder, and I disabled "the airports" from FTX England/Scotland. This works fine with most of my airports however using UK2000 EGCC I get an error message in GSX when I try to open the GSX menu from the gate saying its "issolated" (and it is indeed using the correct AFCAD). I found installing an older AFCAD for EGCC (made for FSX) the problem dissapeared.
I raised the issue at the UK2000 forum as my initial guess was the problem was with the latest version of the AFCAD, however the developer ensured me that the AFCAD was indeed correct, and all he did was recompile it using the P3DV4 SDK BGLCOMP.EXE.
Hence it seems that GSX have problem decoding (some) P3DV4 compiled AFCADS?
