Error on loading with simVR mod in JustFlight Piper Arrow III

[Shmark]

I have followed the instructions to install the simVRlabs VR mod to the JustFlight Piper Arrow III, but I get an error message when I load the aircraft. The relevant lines from the log.txt:

The error message in-game just repeats whats here (between the horizontal lines). I can post the whole log.txt too if thats more helpful.

Is this a known issue? Is there a fix? I'm happy to dig into files and stuff if needed, as long as I have some direction.

 

Thanks yall
