We are trying to sort it out this with PMDG privately.
I can only imagine there must have been some kind of communication mishap or misunderstanding, but I can assure you we have been in contact about this, and I'm sure that, as soon this will be cleared up, we'll find a way to have the two programs working together, just like it's already working with the FS Labs A320, so I proposed to use the same method with the 747.
