Hello, I have a big problem with my 747-400 PMDG.I have FSX SP2 and the 747X with V2.1.000.40 update. No error message in the entire installation process. 1) When I load the plane up (via Free Flight, no saved flights, no saved panel states), the QNH setting on Altimeter change to 750 and the flap on ECIAS displays "30", even if the flap lever is at zero position (the flas are actaully up too).2) During the flight the QNH cannot be changed to correct setting using the knob or the QNH (I try to click "B" but nothing happened), and there was somethign like TCAS warning on the PFD. (altitude bug displays -7500).Please PMDG staff help me to find the solution...Somebody suggested using older 747X service pack version V2.1.00.0031 to fix this problem done, but on PMDG website only provide V2.1.00.0040.Could you help me please....I want fly with this great airpalne with my altimeter fix!!!Thanks to all!!!Alby
