Wallacei Component Not Working

I am having trouble with my Wallacei component, every time I try to add it to the workspace it comes up at “Method not Found…” (See screenshot attached). I googled and cannot find an answer to this—do I have to re-download? Let me know if anyone has any idea!

Please make sure you have installed either Wallacei version R6 or Wallacei version R7- you can not use version R7 with Rhino 6 for now.
