SheetCam 8.0.0 license evaluation error (rotary plasma)

Hi, I have installed SC 7.0.21 (licensed) it works great. Today I installed SC 8.0.0 on the same computer to check bug fixes on rotary plasma plugin. So, I have two versions on the same computer.
I used the same license file for new v.8.0.0. and SC allowed license installation.
I tried rotary plasma plugin but I got this error:

I tried to reinstall and install again but I got the same error again.

I wanted to try SC new automatic nesting module but could not find the icon. There are two icons import-export .nest but I cannot see automatic nesting button.

Kind regards,
Adam

please clarify, are you attempting to use a v7 license on a v8 install ? If so, this combination is not supported. v8 must use a v8 license, and any plugin key is matched to the base license file, thus using a v7 plugin key with a v8 license is not valid either.

re. v8 new feature tutorial, please see videos here - Support Manuals – SheetCam LLC

Yes, I was attempting to use my license v7 on a v8. I claimed some fixes on v7 and I was expected new v7 release with fixed bugs.

I’m not aware of any bug fixes between v7.1.40 and v8.0.0, there were only new features added.
