Hi there, Once I install the aircraft, I can start it up once, then every other time I try to load up the NGX, crash to desktop with fatal errors and everything, its when i click fly now, it comes up with the white box but then after 1 percent it closes again.

Navigate to this file: "....\Microsoft Flight Simulator X\PMDG\PMDG 737 NGX\737NGX_Options.ini" and remove the line I have bolded. Will normally be the 3rd line from the bottom. ......SoundGroupValue.4=1.00SoundGroupValue.5=1.00[Aircraft Config]FixedConfig=[Panel State]StartupPanelState=XXX[FMC]LastPosLatLon=N5705.6E00950.0

Maybe try the above instructions first. A shot in the dark, but worth a try maybe.

Hi Zach, Thanks for that, but unfortunately it never worked.

I'm sorry, Ross. Perhaps someone who has experienced the issue will have answers.

Right now, I have to reinstall every time I close flight simulator, not much fun.

Have you submitted a support ticket? They've been great about answering my tickets within a couple hours.

I'l give that a go, thanks, Zach.
