Yes, I am sure ....
We are speaking from Berlin Brandenburg V2, and not from Berlin Brandenburg V1.
Airport Berlin Brandenburg V2 XP | Aerosoft Shop
With V2 there are only 2 folders included.
The folder ... 00 - Seasons and the folder ... 01 - Airport.
Berlin Brandenburg V2 is a new fullversion. You have to delete the older three Berlin Brandenburg V1 folders before you install the V2.
I hope they will fully revise the turboprop simulation including beta range and a way of setting up your controls for turboprops like with the Majestic QQ400. I'm also hoping for revised water physics in the near future. They're just as bad as the turboprop implementation, if not worse. Can't wait to take the Twin Otter out for a ride, but take your time with this product, there's no rush. This will be a day one purchase for me
