HDRI editor not active in license activated Keyshot 5.2.10

Hi!
My HDRI is greyed out and the thumbnail is inactive in my (current) version of Keyshot.  Nurbs too.

Everything else seems to work fine,render,saves etc.

I'm running a Boxx with 8 cores
Windows 7
8gigs ram

Zbrush 4r7
Keyshot 5.2.10

Thank you!
I apologize if my query is improperly formatted.

I guess the zbrush plugin bundle is only HD and doesn't include HDRI editor.

Correct. It is included in KeyShot Pro and higher.
