I'm having the same problem and it kinda looks like Oct 25th update broke something for me. On the 23rd (running the previous, 10/21 update) I tried flying from FlyDesign EPGD with a GSX profile from flightsim.to and everything worked without issues. Today, on version 10/25, I tried the same airport + the same stand and got the afcad error. The only difference is I've been using PMDG 737 for the first flight and Fenix A320 for the second.
