Hello, First post. 2 weeks ago I purchased the NGX, At first I installed it and the first flight resulted in a CTD.But, in the last 2 years I added a whole lot of add-ons, tweaked FSX by replacing the uiautomationcore, replaced "lost files", FSX.CFG etc etc. So I uninstalled FSX (which did no worked out fine.)Did a fresh windows 7 64 bits install. Installed FS and both servicepacks, 2 sceneries, REX 2.0 and the PMDG 737 NGX.Worked like a charme until now. I was practicing circuits at EHGG and suddenly a CTD. I restarted FSX, loaded the 737, then a problem. No initialisation of the NGX. Waited 1 minute, rebooted, did a restore, Nothing helps. I replaced the original backup of FSX.CFG. Nothing.With all the default FSX planes no problems. Below a screenshot of the panel. Hope that somebody can clear things out for me. Regards, Joost de Wit

Hi Joost,I wonder if this might help your issue.http://support.precisionmanuals.com/KB/a92/dllxml-information-and-troubleshooting.aspx Cheers

While it should not have failed like this... have you tried uninstalling the 737, THEN deleting (maybe 1st backing up the PMDG directory), and then re-installing ? If nothing else, it might get you back up and running again... (till the next time it Crashes out on you). If you do get it running again, then try backing up the PMDG directory. If it fails agaian, deleting the PMDG directory, and then restoring from that backup. This might isolate the cause, as some form of corrupted file in the PMDG directory, ?? Just a thought..... my 2 cents worth, probably worth preciseley that !!

Hi Geoff, Did not reinstall the 737 yet. If I have to do that I will take your advice and back the directory up. Thank you for your advice. Joost

Problem solved. Unplugged the USB headset. Standard speakers in soundconfig and voila praticing circuits at EHGG again.

Problem solved --FREAT --- buy why should unplugging your USB headed have been the solution ??

I really don't know.It was not only unplugging the headset but also changing standard audio back to speakers in windows and in FSX. Maybe a problem with my USB hub.

Joost,your not the first to report an issue with an USB hub. Interesting that it causes a problem for some, glad you got it sorted. Cheers
