Sorry for that, included now.
Yes, after the "load up dead', I uninstalled both 744 and 748. After the re-installation, I updated the 744 -> fixed the liveries -> updated the 748.
And both models didn't work, even with the PMDG livery.
Thanks for all PMDG staffs working over the weekend. I am having the same problem and my P3D version is 4.3.
After the update, I have got a notification saying that there is a livery error (the entry in Aircraft.cfg is deleted but the texture file is still in the P3D folder). Just to see if this can be a hints on what's going wrong.
Cheers,
