PMDG 777 fuel problem.

[jaspertillaar]

Hello.

Almost everytime after takeoff with the PMDG 777 I get a message which says that I'm not allowed to change the fuel load in flight and when I click on "close", FSX
crashes.
I also had this problem with the NGX but I found out that I had to configure my fuel load with the FMC before I start FsPassengers.
I do the same with the 777 but a few seconds after takeoff FsPassengers seems to think that I'm changing the fuel load.

Does anyone else have this problem?
Does anyone know how to solve this?

Thanks.
