Good afternoon Litjan, and thank you for your prompt response.
On your advice, I first tried in-game disabling all plugins except the Gizmo64 plugin, which I know IXEG needs in order to run. It did not fix the issue. There were a couple of other things I noticed as well. One from the log.txt file (in addition to what you referenced, which is a message I get when exiting X-Plane 11), and another from the IXEG console in game.
From the IXEG console in game, I get a red text when the aircraft loads which says the following:
356.456: Run(xp): OnBeforeReboot: [string "ixeg.733.config.lua.ral"]: 11
9: attempt to index local "configfile" (a nil value)
I don't know what the above message means, but I'm guessing it has something to do with what's going on. I should mention I understand that only the popup IXEG 737 main menu can be used to configure the aircraft. Whenever I use that menu to configure the aircraft, eg. adding winglets, it'll sometimes work, but then the buttons on that menu will become unclickable after making any change. Something else I noticed, this time from the log.txt file:
0:04:24.229 I/OVR: Reading VR conf file: Aircraft/X-Aviation/IXEG 737 Classic/B733_vrconfig.txt
0:04:24.229 W/VRCONFIG: Could not find vr config file: Aircraft/X-Aviation/IXEG 737 Classic/B733_vrconfig.txt
0:04:24.229 W/VRCONFIG: VR Config data file for Aircraft/X-Aviation/IXEG 737 Classic/B733_vrconfig.txt is not valid!
0:04:24.229 W/MANIPS: Could not find vr config file: Aircraft/X-Aviation/IXEG 737 Classic/B733_vrconfig.txt
0:04:24.229 W/MANIPS: VR Manips file for Aircraft/X-Aviation/IXEG 737 Classic/B733_vrconfig.txt is not valid!
Does the above have anything to do with what's going on? I'll attach my latest log.txt file as well. I'm really hoping you're able to fix this, because not being able to use the popup IXEG 737 in game menu makes the aircraft unusable.
Thank you,
Fropa
