Ok so I've done a test right now, and it works... almost perfectly well!!!
No black screen etc. ! But one problem still seems to remain though
See by yourself:
However, this is just unbelievable... if i go to another airport by the world tab, the problem disappears completely!!!
Second very little problem: navsim function is out of service, and when loading the airplane, an error message pops up, telling that nav, waypoints and airport data couldn't be retrieved... anyway, VOR instrument is fully functional, so I don't care.
