Hi Umberto,
I've posted a reply to your post at avsim and included the error report that may help your team. But you may have already received some of these since you've mentioned that the content error was reporting that the textures in the catering were not loading, and they are loading perfectly. That's what I don't understand and I want to thank you for bring that point to the forum that even your development team doesn't understand why it's reporting this error but the textures are showing up perfectly. I haven't had any problems with the GSX while running it, and yet after I close the sim, I get this content error report crap that nobody seems to know anything about nor understand. I understand some of it now and found one error that was reported in the aircraft.cfg file. But the other stuff I don't understand.
By the way, has your team gotten around to correcting the gate parking spots at KDFW?
Ken.
