Hello,This last days when I try to load the Load editor I get a fatal error saying: " Could not detect a valid Microsoft Flight Simulator installation".Well it is right there under its nose.Does some one knows where this is coming from, never had this before.Is it easy to re-install the PMDG 747-400???Perhaps that would be the best thing to do.Carlos

Thank you RyanI knew something like this was available, but didn't know where to get it.The Loadeditor works fine again.This must has happend when installing the SP1 for FSX.I looked in the registry and could see that there was something missing, but didn't know how to fix that.Carlos
