Recently I have been having the PMDG_737NGX.DLL crash when selecting the plane. After searching the forums, I saw that there is sometimes a problem with the Saitek X52 Pro, which I had been using without a problem (also using the saitek software without problem) for years with this add on. I've also had FSUIPC installed for months without problems, though I recently purchased the license - that said, I've still completed several flights in the NGX with the X52 and the registered version of FSUIPC 4 without a hitch, until today, when I couldn't even select the plane. I disconnected the controller, and upon restart was able to select and load the NGX without problem, so I think I've at least isolated the x52 as the culprit. I deleted and rebuilt the cfg and loaded the NGX without the controller, ok, then restarted with the controller, same problem. 

Although I have presumably narrowed the problem down to something to do with the x52, I have literally used it for years, without a problem, so I am at a loss for an explanation. Short of ditching the Saitek software and simply using FSUIPC to program the controller, which I was going to eventually do anyway, does anyone have any thoughts or suggestions?

I've still completed several flights in the NGX with the X52 and the registered version of FSUIPC 4 without a hitch, until today, when I couldn't even select the plane.

So did you run AppCrashView or look at the Event Viewer to see for sure whether it was the PMDG_737NGX.dll that caused this particular crash? I agree that the PMDG_737NGX.dll faulting module is related to throttles but we have had several others who have fixed this problem by updating or uninstalling and reinstalling their video card drivers. I know PMDG has been looking into the crash with this particular dll and can sometimes reproduce the crash but cannot pinpoint the cause. I suspect you may be on to something regarding the fact you are using the Saitek software. You shouldn't use both. It could also be your USB ports need to be updated and there is a conflict with the port that you have the controller plugged into. Try downloading and running a driver's update program (I have been using Driver Scanner or Driver Genius to update many of my hardware drivers, like USB ports, system bus, the Intel Chipset, etc.). The USB ports are always updated when they find bugs or when they find a way to make them operate more efficiently with your version of Windows. It's freeware to scan, payware if you want the program to download and install the updates (if you are computer literate and you sound like you are, you can simply Google for the updates found, download them and install them yourself).

 

If that does not fix the problem, then you are probably going to have to submit a ticket to PMDG and see if they have found a solution yet (don't think so or it would be all over the PMDG forums). Hopefully someone will visit here and tell you whether they have problems with the Saitek X52 Pro too. AVSIM has a controller forum in the Hardware section and you might find something there too. If you do find a solution, please post it here. Thanks and good luck!

 

Best regards,

I did look at the Event Viewer to confirm.

 

Thank you very much for your suggestions; I know I have the latest video card driver, but as to the rest, I couldn't say for sure, I haven't checked in a while, so I will try your suggestions. It's frustrating, because I'd reached a level of comfort with my set-up's performance for quite some time, and then this little problem rears its ugly head out of nowhere. The nature of the beast, I guess.

 

Thanks again for taking the time to post such a thorough and helpful reply!

For what it's worth, I updated everything, but the problem persisted until I deleted the programming software. I would have attempted to program the controller through FSUIPC, but I couldn't find a definitive answer if the multiple modes could be programmed with it, so I reinstalled the Saitek software, and it seems to be working again, for anyone else who stumbles across this problem.

Thanks for posting your solution. I use the software that came with my Cyborg controller and I have never had any problems.

 

Best regards,
