Hi Mark,

thanks for Your detailed answer ! At the meantime, I have purchased the DX10 fixer too.

Trembling, I've loaded my flight, and soon, I could see a AI-LTU L1011. with completely strange textures. Tough luck - I thought.   :(
But as I have seen the other AI-planes, which looked also gray before, I found that they all had normal textures and also functioning wing and strobe lights . Tthe LTU L1011 I could fortunately replace by another model, which now works perfectly. So yet again lucky!  ;)

And of course, it also fixes the CS L1011 lights, as You said.

It was important for me, to keep my retro ai-traffic at DX10, because it's really great, "sitting" in the CS L1011 and watching also L1011 and other good old retro AI-aircrafts all around me at my airports.   :)

Thanks again and
  Kind Regards !
