[Guide] Ripping models from Sketchfab

I don't think this is working now...

After installing all the things to make Blender work (because I had an error message, I had to install Visual C++ from 2008 !, most recent versions doesn't work).

Now, when I import the osgjs file, nothing happens, nothing appears...

Is it normal that the osgjs file only weight 12kB !? I mean it's impossible for a 3D model to be that light...

I've read EVERY PAGES of this thread and a lot of people said they have this problem, but no one answered...
