I get black screens in my 747 Pax edition, I am not sure if it is in the F. But it is in the PAX. I have APU, GND PWR or ENG. But they are still black. I have tried to shutdown the aircraft and start it again, but it is still black. I cant turn it on in anyway! What's wrong?

Its not validated. Uninstall and re-install and make sure you enter the exact details and password you used for your account when you PURCHASED it.

Are you sure? I validated it and it was accepted. The screens work for a while a then they turn out. It was not like this before.

Mr Nameless,Please sign with your name as per the forum rules. Thank you.Either Randy is right or you havn't got the electrical system correctly running. But as you say you see the DUs for a while before they black-out you probably have a validation problem. But then again it all depends on how long that while is! ;-)Hope it helps,
