Hi
My mistake , downloaded the Enterprise edition of the Octane Server from the Realease forum post instead of the Download Page.
Though this is the first time Blender crashes because of a different license instead of just warning the licesnse is invalid.
The new features are awesome , instant rendering after re lunching , no wait. The duplicate features works great without freezing.
And the Undo seems to work well now!!!
Only one issue head when installing Blender. Avast reacted to the file as being infected:
