Same problem:
the game freezes in combat in White run:
    Unable to call RegisterForSingleUpdate - no native object bound to the script object, or object is of incorrect type
   [None].DualSheathReduxEffect.RegisterForSingleUpdate() - "" Line ?
   [None].DualSheathReduxEffect.OnUpdate() - "DualSheathReduxEffect.psc" Line ?
Like i said before:
... i run Dual Sheath Redux Patch.jar.
What can I do?
