Also, it will be infinitely easier for anyone to help you if you post your GH model:

In Kangaroo Physics it says the invalid node type was connected to the dynamic input, Check item 0. And to me it seems correct. Normal Mesh as Runnie was using. I tryed different pypes of meshes from flat planes and simple curved ones to more complex and refined but it still says the samw. And the code is not running. I am totally stuck here. 
Could you please advise what seems to be the problem. Thank youâŚ
