Dear form editor.
Greetings.

I have google sketch-up 2015 pro.

1. I have installed the plug-in from the presences section / extensions : install extension
   after downloaded from the website

2. restarted the program for activating the plug-in

3. message pops-up as following "you have to visit the website to make the plug-in working"

and the normal website as follow

RoundCorner | SketchUcation

(sketchucation.com)

which is the first step of installation, which is pointless.
