Hello all,When I start a flight with the PMDG 747 everything seems to work fine.When I taxi away from the gates the screens (pfd etc.) shut down....What am I doing wrong?Regards,Mathijs.

Sounds like a classic case of your product not being validated.I'd suggest emailing support if you have a legal copy, or running from here if you don't ;)

Hello,Thank you for you reply, I've got a legal copy so that's the case why I didn't understand the failure.I'll contact PMDG and keep you informed.Regards,Mathijs
