I added the FS Copilot entry into the EXE and DLL files as FSDreamTeam's Honolulu scenery somehow overwrote these entries and caused FSX to crash when I opened the FSINN UI from inside FSX. This problem was very nasty to isolate and took me several days to understand. I hope you can help me get the buildings back for my sceneries KFJK KLAS and PHNL!
Your DLL.XML is fine.
It's your hand editing of the EXE.XML file that has been the cause of the problem, for the following reasons:
And here's my EXE file content.
The main problems is: FS Copilot.dll it's a .DLL so, you can't add it to the EXE.XML file! It should be present ONLY in the DLL.XML file.
And, while editing the EXE.XML, you also forget to open the <Launch.Addon> tag, you only closed it.
This has made the whole EXE.XML file invalid so, FSX will not load anything from it, which is why buildings have disappeared, since our Couatl module is not loaded anymore.
You should also remove the FSUIPC section (it's .DLL) from there, which is also something that you surely added manually.
About the crash problem, AFTER you fixed your XML file, Try to launch the PHNL installer again, so it will get a new version of the Addon Manager .DLL we posted today, which *should* work better with FS Copilot.
