Karamba | Crashing with Assemble Model (Karamba) in Form Finding of Shell

Hi, 

I am a newbie in Karamba. I follow this video http://www.karamba3d.com/form-finding-shell/ for Form Finding Try out. But whenever I plug the Element of Mesh to Shell (Karamba) to the Element of Assemble Model (karamba), Rhino crashes. I cannot open the example file from the website neither. I got the student license for Karamba. Can you help me to figure out the problem?
