OK just after my post, I did hear from CURIC on FB chat. There was a bug and he provided a Ruby script that solved the problem. Only had to run it once.
Pretty impressed.

I am disappointed with Curic plugins in SketchUp 2020. From extension manager you are sent to a Gumroad page with no information other than an icon and price tag. My bad, I paid $99 for the Studio bundle because a video I saw for Curic Section showed a slider controller that looked to be the answer to my needs in a large project I am on and there were some positive reviews on the YouTube page.
After he installation (Windows 10 PC , SKU 2020) I find there is no slider. I further discovered that Curic has no way to be contacted for support other than either leaving messages in Facebook or comments on the YouTube page. The only reply I had was in YouTube asking what version SKU I was using but nothing after that.
Has anyone had a similar problem and found a path to customer support for a pricey plugin?
Thanks.
