Hi,My laptop just died so I am using my wife's laptop instead. I have reinstalled fs9 and then the PMDG 737-600 and then the 737 - 800 in that order. Trouble is my panels are blank and I cannot access the FMC. I can get to the over head but only via the "View" menu. I am sure that this has been discussed before but I cannot find it. Any Ideas anyone? I want to reinstall the 747 but I would really like to fix this first.Gerry

Gerry,You'll need to re-validate you're install. Contact [email protected]

Peter,Thnaks for the prompt reply. I have done that but do I only need to revalidate if I have the downloaded versions? All my PMDG aircraft are the boxed versions.Best wishesgerry
