When i load the 747 and go into 3D cockpit, within seconds all the MFD's turn to black screens? Does anyone else have or had this problem and what can i do to fix it.Frustrated Qantas pilot

Hi,This is not an FS2Crew issue, but I know the problem and the solution:You have a license problem with your PMDG 747 aircraft.Please re-install the PMDG 747 aircraft.Best,Bryan
