I can only repeat and confirm the problem doesn't happen. Just check all the other threads here: all that reported a problem with Live Update at LSGG all reported the latest Live Update fixed it.
Try to remove the .BGL manually from the Addon Manager\Fsdreamteam\LSGG\scenery\AFX_LSGG.BGL
Then run Live Update again.
Hi. I eventually upgraded to P3D v4. V3 was becoming obsolete. I can now confirm that all is working as it should.
Ty!
