[Sean Brown 0]

When I first load with PMDG 747 they are seen to be fine but when I switch a Default  plane then switch back to they won't load at all( In-game where 747 fail to load as second time)I did follow the PMDG General from(FSX: SE) and as well as trying to uninstall and reinstall and run and/or Repair  the SDK and 3 others too but not working even Run as administrator on FSX with the same thing to my PMDG 747. .

Hi Seanymack,

Welcome to the forum.

It is not recommended to load a second instance of the PMDG aircraft into the same FSX session. If you need to switch aircraft for some reason, best practice would be to close FSX completely, restart it and then load a different aircraft.

Please see the Intro Manual. It covers this exact situation.
