Hello,
I've tested the conditions for the crash and I can provide more information for you.
What I have:
1. The fresh Windows 7 64 bit installation. No FSX, no P3Dv2, only P3Dv3. I have no Migration Tools, only 2 symbol links and 2 registry keys in order to fake old P3Dv2 installation.
2. I installed ORBX Global series (FTX Global, Vector, LC EU)
3. I installed most of FSDreamTeam airports and all airports of FlightBeamStudio and GSX.
4. I installed Ultimate Traffic 2 and Ezdok 1.85.
I noticed, my installation randomly crashed every 10 - 20 minutes. I noticed too, I can 100% force this crash, if I want.
How did I do this:
1. Load PMDG 737-800 WL Delta an Gate E11 on KIAH (FSDreamTeam)
2. Connect GPU.
3. Click 10 - 20 times an Main menu -> Add-ons -> Addon manager and some times other menu item such as Settings etc.
4. Simulator crashed.
What I tested too:
1. I disabled Ultimate Traffic 2 and Ezdok in exe.xml, but P3D still crashed.
2. I disabled GSX in Main menu -> Add-ons -> GSX -> Disable, but P3D still crashed.
3. I disabled couatl.exe in exe.xml, all FSDreamTeam and FlightBeamStudio are not usable but P3D still crashed.
4. I uninstalled GSX, Couatl and Addon Manager. Then all FSDreamTeam and FlightBeamStudio airports are not usable, BUT I have NO crash!!!
5. I installed Couatl and Addon Manager explicit without GSX and I can use all airports and all works fine. But I have no GSX. :-(
I must uninstall GSX in order to have a stable simulator.
I noticed more other errors in Couatl in KIAH or in KSFO HD. I send you the logs. Probably this errors are not responsible for this crash. But you should know it.
I love GSX. I hope, you will find this error an I can use this fantastic product again.
Kind regards,
Vadim
