The line above your posted one would be interesting then...
Code:
[18:55:32.910] DEBUG SODE.FOLDERMANAGER : Extracting SimObject Paths from 'C:\ProgramData\Lockheed Martin\Prepar3d v4\simobjects.cfg'
[18:55:32.910] DEBUG SODE.FOLDERMANAGER : 'C:\Users\Jeffrey\AppData\Roaming\Lockheed Martin\Prepar3d v4\simobjects.cfg' does not exist! Extraction of SimObject Paths not performed...
First SODE checks simobjects.cfg at C:\ProgramData\Lockheed Martin\Prepar3d v4, then it checks the AppData\Roaming path. In my case, the last one does not exist, but the first one is read.
What is defined in your simobjects.cfg at the ProgramData location?
EDIT:
I think I know what the problem is. You are placing an aircraft through SODE. While this is technically possible (an aircraft is also a SimObject), most aircraft are defined with an aircraft.cfg file, while "true" SODE SimObjects uses sim.cfg.
This SODE version only scans sim.cfg files and checks the existance of the models listed in those sim.cfgs.
When SODE then checks for existance of your aircraft, it is not found internally and that's why you get that red cross!
So with this SODE version, you won't be able to load any SimObjects (using aircraft.cfg) directly anymore, only SimObjects that are defined through a proper sim.cfg.
If that's the only aircraft you use for static placement, you can create a little SimObject container for that using a sim.cfg, then it should load.
