ArkoAI - Rendering problem

Hi, I would like to buy a subscription to this plugin, but before I buy it, I would like to try it out.
So I installed the ArkoAI and after that I logged in to ArkoAI (in Rhino). I see that I have 30/30 rendering, but when I press the button (Render) nothing happens, what could be the problem?
Thanks you for your help.
