Do you have SketchyPhysics installed? If you look back through the thread you'll see that others found sketchyPhysics caused problems with this plugin.

I just tested it on my Mac with SU2013 and it works fine. You didn't answer my question about having SketchyPhysics.

Dave Thank for your help after disabling V-Ray rendering plugin the roof plug works fine.
The Lamella plugin works great it's a pitty the hidden sample beam is not compleet with all uniek parts and Isolated from the rest.
The workflow after opening the rubyconsole is not CNC conform. But overall it great tools for building one!
Thank to Tim Warner.

Dave,
As I wrote I had a clean install which is not holding any plugins except the roof one.
It was working in windows sketchup 8 and not in 2013.
After excuting the roof plugin sketchup was more sketchdown.
I was asked to send a error file thats it.

Still not working in a clean 2013, it is in sketchpro 8?
Got a complete hangup with a error report back and had to start sketchup again.

Error after running ruby?

lamella_roof
Error: #<NameError: undefined local variable or method `lamella_roof' for main:Object>
(eval)

Sounds simple to solve but how?

Thanks Dave, I install sketchpro 8 back and it is working.
Has someone used it win Sketchpro 2013? It's not working?

The plugin Lamella_roof is not working at all under the new Sketchup pro 2013.
Sketchup itselve stops completely.
I had no problems with Sketchup 8!
Has anyone else the same experiance when upgrading to version 2013?

Some help please?
