Can't get Kangaroo menu items in Grasshopper

Hi, new to Grasshopper and Kangaroo. Have been using Rhino on and off since version 1, now on v5.

I have copied/pasted kangaroo2.gha and kangaroosolver.dll into the folder

C:\Users\mj\AppData\Roaming\Grasshopper\Libraries

which comes up as the Components folder for Grasshopper. When Grasshopper starts I can briefly see something being listed as loaded in the Grasshopper status bar, but I don't get any Kangaroo menu items or panels. 

Thanks for any help getting this working.
