I found- that in some cases- like the Antonov airplane- that some of my functions- like the wheel bogeys- does not want to retract. On my SR 71 and Airbus A 300- I found that none of my instruments are functioning at all- no display on my visual screens also.
What can I do to get my cockpits functioning again? This seems only on certain F/Sims of certain aircraft that I downloaded as additives.
