Corona for C4D demo, crash creating material

I’ve downloaded the C4D Corona demo, but when I try and create a material I get a crash each time. This is from R18. I’ve attached a screenshot of the dialog which comes up.

moving to C4D bug reporting section

Hi, can I ask you what version of Corona you downloaded?

Thank you
Nikola

The C4D-Alpha v6 hotfix one for OSX.
