hi everybody!

I'm trying to import materials from Kerkythea into Sketchup library, unsuccessfully. I'm doing as follows: with the Sketchup open, I'm going in "Plugins/Kerkythea Exporter/Import KT materials" and I'm selecting the KT materials file (eg. NK metals.mat.zip). When I press OK button, nothing happens. Even after pressing "KT Materials Update/Detach", nothing new happens. I go in the Sketchup materials library to see if it is in there but, I see no new material.

What should I try different? What's wrong? If any of you help with this deal, I'd appreciate.

Thanks in advance.
