The fltplan I was trying is the one from ronzie's postI've headed this to iFly forum once but they couldn't find out why.This is the video,I've loaded sucessfully the flightplan before installing PFE. And I tried to reselect the departing runway again,it failed.

The forum no longer supports attached zip files. The iFly plan I posted may contain extra end of line characters that the actual plan does not. From DIRECT,3,BCN,0, to before N864,2,DIKAS,0, is one line and you have to edit that in wordpad with the wordwrap option turned off. In other words starting from that route section the waypoint lines are really one between waypoints.The file name is EGGDEIDW.FLTPLAN. Either way you have enough to compare FMC plans.Mike: 2.4.0.17 is said to be stable taking into account some Navigraph conditions that were discovered and the latest Navigraph data. Keep checking Navigraph for data re-releases.I doubt if there might be a problem with I-Fly FMC procedures (1310) but here is another link for some i-Fly models (free):http://planepath.com/html/ifly.htmlhttp://planepath.com/html/dafif.htmlI downloaded the PFE manual from Aerosoft (pre-release) and it states that you have to compile a plan for PFE use but it goes into its own folder and I did not see any reference to modifying other plan formats. I saw no reference to FSUIPC use which might affect the navigation of some aircraft.I agree that PFE should not be affecting the flight plans and navigation data used by aircraft.

You're selecting on the arrival side of things as far as I can tell... And this is hardly a good example because you appear to already have a complete and normal plan. It's when you start messing with it that it gets messed up. But anyway, I went to the iFly Forums and tracked down your thread about this, I had to laugh. the thread starts with "After installing fs2crew I have some trouble, I don't know if I have done anything wrong or not. Before having fs2crew I've used ifly 737 everyday and never had this problem.".So, it's PFE's fault, FS2Crew's fault...:PI also read about KMDW and how you selected a SID/STAR before selecting a runway. Selecting a runway acts as a filter, so you select it first and then the FMC will list the available SID/STARS for that runway. I think your best bet at this point is to start anew, again, and try and keep it all working a little longer. Eventually you'll get the hang of it and no longer need contraptions such as System Restore.:(

Oops I meant the arrival not departing :blush:Yes, at that time I installed both PFE and Fs2Crew at the same time. Because I pretty much believed that PFE doesn't touch anything to either iFly or FS, it only could be Fs2Crew. But I was wrong.

Anyone have any ideas?For some **** reason my computer lost the previous restore point so now I'm stuck with this problem and uninstall PFE doesn't help anything.

Anyone know what key does PFE register to the window (regedit) when installing? i'm thinking it might be registry problem.
