I also am having the problem with missing buildings,etc.When I installed DFW the first time,Addon manager is installed.but no COUATL.I re-installed KORD,and the COUATL reappeared.I then re-installed KDFW,and now the COUATL is missing again!
If your KORD installation comes with online self-update, that's just plain impossible to happen, because the couatl.exe it's the SAME, since it fetched online by the installer from the same location as KDFW.
If, instead, you have an old KORD installer, without online update, perhaps your ANTIVIRUS has mistakenly decided the current version of couatl.exe is a threat.
To fix this:
- Turn the antivirus entirely OFF
- Reinstall KDFW - Don't launch FSX yet.
- Configure your antivirus to ignore the following files:
YourFSXFolder\bglmanx.dll
YourFSXFolder\fsdreamteam\couatl\Couatl.exe
- Turn the antivirus back ON
- Launch FSX.
