I installed GSX/L2 P3d-V5 and everything was fully functional, yet after an update about a month ago, when I try to board pax it freezes and I have to restart GSX. I can only do two GSX commands (Gate docking and Pushback) nothing else works, the other options are not functional (I can see the window, but GSX seems to be stuck with no signs of any progress when I try to board/deplane). I am using the PMDG NGXu when this happens. Any suggestions on how I can rectify this error?
