Can't render PBR materials with blender

Hi,

I just installed Radeon ProRender on my mid 2015 MacBook Pro. I opened blender 2.79b and I created a very simple PBR material for the default cube. Unfortunately the render found this error and can't render the scene:

Re: Can't render PBR materials with blender

Which version of RPR do you have installed?  This works for me with the latest.
