The error log you posted now doesn't have anything to do with the first one, which was related to the Twin Otter possibly lacking a GSX profile. This one looks like you haven't installed the latest update which fixed that error happening with planes with an AES intelliscene profile.
Dear Umberto
Yes, I know the two errors probably have nothing in common. I'm just reporting the errors I have on my system in order to get some help.
First, I didn't see passengers when using the Aerosoft Twin Otter Extended. And no, it wasn't a GSX profile missing, because I used to have a profile for years and meanwhile, I tried several profiles for the Twin Otter from the forum (and I also did a new one from scratch). All of this didn't help, the error persisted.
Hoping that your updates might fix the error, I downloaded GSX version 3.3.0 yesterday, and
after uptating to 3.3.0, I got the other error message when loading the Twin Otter. So as you can see, I also did install the update (or at least think I have; I've run the Coual Updater now three times...)
Kind regards
Michael
