August 29, 201114 yr Has anyone had this problem. Let me explain. In 2D view no problem - every screen works. In VC view, no display unit video and no knobs. What can cause this problem? What have I done about it? I downloaded the authentication code again as instructed, used 'run as administrator' without success. I then uninstalled PMDG 737 NDX and then reinstalled it. Same problem. I would appreciate help with this.regards Michael
