Thank you for trying to help,
It's the old PMDG 747-8i (not the freshly relased fancy one, this I use in P3Dv4, where everything works just fine),
I just have a PMDG, a couatl, a GSX, and a RAAS entry in the Add-Ons Menu.
I have to tell that to save VAS I usually disable all add-on scenery which wiill not be used for a certain flight in the scenery.cfg, so it's possible that a scenery is active in the Addon-Manager but is not currently installed in the Scenery library, but also disactivating everything does not help. Of course, GSX and GSX2 expansion always stay active)
Is there a way to manually stop the bglman module?
Best regards
