I have had the ported Carenado C206 (my favourite A/C) for some years, and it worked a treat for a ported model, but I have had to reinstall after changing my OS from XP to WIN7, and now the mixture control does not work. I got the patch, even though it say Saratoga sound, as it claims to fix the mixture problem, but it did not. The reason I liked the 206 so much was that the mixture and the prop pitch worked so well.Help anyone? Teecee.

Have you tried re-porting it? Be sure to clean out all the 206 files first before reinstalling them.
