new ZGGG issues

It's quite unbelievable to not find something about this after hours of search considering it might be quite common. Anyway... I installed this new ZGGG scenery from Jan Martin's "Jetway & Terminals" package.... looks quite nice btw. But somehow I have problem with AI-traffic. I've followed the install instructions including copying those scenery/asia/scenery files and downloaded the afcad file, but don't seem to see air traffic.... not even in the old ZGGG airport anymore. Did I miss something.... do I have to edit every single flightplan or is there an easier way??
