Material Editor shows black slots with Corona v.1.0

I have the problem for Material Editor Slots. It’s doesn’t show picture. How should i do?

Make sure that renderer for material editor is set to Corona: Render Settings>Common>Assign Renderer>Material Editor

Thank you for the answer.
I am sure about Render Setup is “CoronaRenderer”

But now i can do it!!!
If anyone has some this problem. Can should do the same this picture.
It work ^^

Hi,
I have the same problem. As you can see the sample slots are black and the basic parameters are still those of VrayMaterials.

Your Corona Renderer not activated
Run render process and choose your type of license

Ok, thanks for the suggestion. But the demo does not activate automatically; so, where to copy the activation code back? I can’t find a place to paste the activation code (It’s embarassing, I know…)

Ok, I’ve solved the problem. It was an already known issue: Activate dialog (and other) broken when using 150% font scale in windows - Corona for 3ds Max :: Issues - Chaos Forum
