I have GTN 750 license, I set it up according https://www.togasim.com/mu2docs/setup/realityxp.html but GTN 750 is "blocked" by black rectangle (see attached screenshot)
Could you check GTN 750/GNS 430 work correctly?
P.S. I don't have license for GTN 650, only for GTN 750 (that's why I'm using GTN 750/GNS 430 combination)
