I've had to rebuild my P3D installation from scratch after something corrupted. Although the sim and my usual aircraft and airport addons are now working properly, FLAi for Vatsim is not. I've installed the FLAi Ops Centre again and let that download the models but the first time I fired up VPilot (latest version, 2.6.10) it didn't detect the FLAi models.

I manually added the FLAi Simobjects folder to Simobjects.cfg and after doing that VPilot detected the FLAi models as well as the sim default ones. However, when I connect to Vatsim every single FLAi model throws an error in VPilot saying it's corrupt and can't be loaded. I have manually enabled the FLAi model matching .vmr file. Any ideas, good people of Avsim?

Anyone?

Fixed it. For anyone who finds this thread in future and was having the same problem...

Something corrupted on the FLAi install. I still don't know exactly what but I've learnt that when P3D starts it imports a copy of all aircraft simobjects it picks up through add-on.xml files into the main P3D folder. By default that's at C:\Program Files\Lockheed Martin\Prepar3D v4\SimObjects\Airplanes.

When you exit the sim, those temporary imports seem to be deleted. For me, however, they hadn't been deleted and every time I started the sim the simobject import failed - I guess because the sim detected those folders were already present.

Delete all FLAi_ prefixed folders in simobjects/airplanes. That cleared the problem for me and now I'm seeing the right aircraft with the right liveries again.
