What can I do, that it works??
Your error log shows that GSX couldn't find any model for the baggage tractor. Since all models are installed with GSX, these are some of the possible causes:
- Some of the GSX files in the Simobjects\Misc folder has been moved or removed. You can fix this by reinstalling GSX using the full installer.
If that doesn't fix it, it's possible that you or another add-on installer has made a change to your FSX.CFG that resulted in losing the pointer to the objects folder. Check your FSX.CFG located at %APPDATA%\Microsoft\FSX and all lines that contains the SimObjectPaths keyword. Be sure that all the default entries are correct. This is how the default entries should look like:
SimObjectPaths.0=SimObjects\Airplanes
SimObjectPaths.1=SimObjects\Rotorcraft
SimObjectPaths.2=SimObjects\GroundVehicles
SimObjectPaths.3=SimObjects\Boats
SimObjectPaths.4=SimObjects\Animals
SimObjectPaths.5=SimObjects\Misc
If another add-on needs its own section, be sure to ADD its path on a new line, starting from SimObjectPaths.6=, etc.
