Problem with constant ENABLE AND QUIT message:
Hello, as many people I also had the same problem with constant ENABLE AND QUIT message.
Solution for me was to place in Fallout.ini, Fallout_default.ini and Falloutpref.ini lines:
[HAVOK]
iUpdateType=4
[Landscape]
fLandFriction=0.4000
This was easy part, next thing was that main conflict with XRE has RAGDOLLS mod so I changed in installed Ragdolls mod in config/Ragdolls/RagdollSetings.ini file this line:
fLandFriction=2 -> fLandFriction=0.4000.
This was problem with me, that Ragdolls mod always changed physics from 0.4000 to 2!!!
Also, start the game using NVSE.
I hope that this helps
