Hi all,When trying to install my 747-400X, an NOTAM comes mentionning this: Your FSX version is more recent than FSX SP1 This product was tested previously using FSX- SP1, Acceleration and SP2. When starting my FSX a fatal error occurs just after my clic on a pop up window to run a file .DLL of PMDG747-400X!!!Is there any solution for this? Many thanks for any response,H
