I've done probably 50 flights with the A300 without any issues but the flight I'm trying to do now causes all displays and flight deck systems to "freeze". The sim doesn't freeze, I can still control the aircraft manually but the autopilot doesn't do anything and the PFD and ND don't show any movement. Some buttons can be clicked but their action have no effect.
I'm trying to to LSGG-LFSB with the LUMEL 8K arrival, ILS Z 15 approach. I've tried the same route 3 times with the same results. Before the last attempt I uninstalled and reinstalled the A300 and updated my Navigraph navdata.
Any idea what's causing this? I've googled and found others having this issue but no real solution.
