Hi Paul. I have the Just Flight - 757 Captain fs2004/FSX boxed for quit a few years now. At the time I flew the MSFS2004 -Century of Flight. Later changed to fsx, and after to FSX-Steam. Is the addon compatible with FSW-Steam? I installed once and it was a no go. Full of bugs/twicks frozen panels, u name it. ANy clue on how (if possible) to make it work on fsx-s? Looking forward. Waitiing to hear from u ,best regards from Portugal
