Laubwerk breaking vray

[wheelz]

I'm running sketchup 2015 with vray 2.0. I have just installed laubwerk and it is breaking vray. Vray will not render at all after I have installed. I can uninstall laubwerk and vray works again. The Ruby console displays the message below when I render. Any thoughts of the cause or possible fixes?

==== V-Ray for SketchUp =====
