After installing the 747F, I load the plane and I can no longer open the lower cargo doors on either the PAX or cargo version. Additionally, I cannot open the upper deck doors either. Yes, I have given unique key assignments to all the doors via the PMDG menu.I can still open all of the left and right doors on the main deck of the PAX model, and the 1 and 5 L/R doors of the Cargo. I tried uninstalling both versions and reinstalling, but this did not solve the problem.Thanks for any help.David

Please refer to 13-10 of your PMDG 747-400F Operating Manual.Best,Vin ScimonePMDGwww.precisionmanuals.comhttp://www.precisionmanuals.com/images/forum/devteam.jpg

I have exactly the same problem! The weird thing is that two of the features work. Both the stairs and the yellow thing behind the aircraft works, but the rest of the features do not work... how come? also I cannot open then upper deck doors on the 744 either, eventhough I have given them assignments

Make sure that your key assignments are not already allocated in FS2004. You may need to check the main FS Control Assignments menu.
