For what it's worth, I've had issues generating LODs too, although that was using xLODGen. Also Access Violation errors.
Stress testing using OCCT revealed instabilities in my system, and after resetting my BIOS to factory defaults I was able to generate terrain LODs.
I've now just encountered yet another Access Violation error, this time with DynDOLOD. I doubt it's a stability issue this time, since the OCCT test passed after the BIOS reset.
It's late, so I won't be investigating any further tonight, but I'll return with any updates.
