Extension on Mac doesn't work?

Hey all,
I’ve been a user of SU for years now and have never encountered a problem like this. I’ve installed Ambient occlusion paid version, I installed, in the Extension Manager it shows up, the tool bar shows up. But the actual plug in does nothing. Am I missing something?

I know nothing about Ambient Occlusion, but did you try quitting then restarting SketchUp after installing it? Many extensions need that to finish setting up.

Yes, No dice. Even the tabs where you’re supposed to activate the extension it usually opens a window and you enter a licence number. The tabs are there but when you click on them they don’t work. It comes from www.Fluidinteractive.com
