Hi Chris! Everything works well now. Thanks for fixing!

Hey guys! Had the same issue with licensing. How this can be fixed?

Yes, exactly. As we're talking about Octane, I meant any action in Octane UI - delete node, make any adjustments to the materials inside Octane plugin, literally anything that is done through Octane's UI. Does it make more sense now?

There is no particular location where it doesn't work, It doesn't work in general in Octane plugin for Unity. For example if I accidentally delete any node, I can't undo this action.
It is not even active (see attachments)
I'd appreciate if you could double-check things here.
