Problen with FSP and PMDG

[Edu]

I send this email to PMDG Technical Support and the answer from PMDG is:

"Because FS Passengers alters the aircraft.cfg file, it causes all sorts of problems with many add on aircraft. Unfortunately, we do not
recommend the use of FS Passengers with the PMDG Products"

My original email is:

"I have serious problems with PMDG 747 and Md-11 for FSX

I install them without problems and I run them for the first time well. The problem is that I have FS Passengers and I start cold and dark
and I inicialice systems without problem.
In a moment, I run FS passengers and when returning to the cabin I only have a black screen. Some times I can return to the program
when I push ALT+Enter one or two times (other times I only have the black screen and all is end). In the case I can return to the cabin the
problem is lost of panels and other parts in 3D cabin and in exterior view, lost of runways, taxiways, buildings, lost of parts of PMDG 747
body and other AI traffic or the horizon flickers.

I have a top end PC so I suppose no problem in this way: Intel core I7 extreme edition, nvidia Gforce 295, 8GB RAM.....

Operation system Windows7 64 bit (the same problem with Vista 32 and 64 bit).

1600X1200, AA 4x, anisotropic 8x (same problem when FSX controls this aplications)

Microsoft FSX SP1 and SP2

Addons:

FS Global 2008
Flight Environment (Flight1)
Ground Environment (Flight1)
Ultimate Terrain USA, Canada and Europe (Flight1)
My Traffic
Level D B767
Pilatus PC12 (Flight1)
Douglas DC2 (Flight1)
C-130 (Captain Sim)
different airports, most of them from Aerosoft.
B377 Stratocruiser from A2A simulations

FS Passengers

I don´t have this kind of problems with others Addon planes such as Level D, Captain Sim, Carenado and others. They run perfect.
Do you have anu solution? Thank you and sorry about my english.
