Hi, I tried to do what suggested and everything is ok.Now I can load the flightplan in 747_400/747_400F/737 FMC.The problem is still present when flying offline and I try to load the FSBuild flightplan in MSFS flightplan load screen. Under FSBuild I noticed that there isn't an entry for MSFS flightplan files.I don't understand why it seems that if FSBuild can save the flightplan in PMDG and many other formats it can't save it in MSFS format under the native flightplan's directory that is under CDocument and SettigsDocumentsFlight simulator files.FSBuild can't transate the file in MSFS format or there is a bug in the program or there is something that I don't know/understand?Thanks a lot,Maurizio Balvetti

Go up to the very top of the program screen. Select "Export to . . " In this menu, make sure the "MSFS 2000/02/04" is checked. See if that won't get it.
