August 15, 20178 yr Hello, I have Prepar3D v4 installed. And ofcourse PMDG 737 NGX base 800900. When starting to fly the 737 I have to fill my activationcode. So I did and the message come that registration is OK. In the FMC is the message that the 737 is NOT registred!! When I activate AV and Firewall are OFF What's wrong? John
