Older Version of Kangaroo

Hi, I am trying to run a script I found online that requires kangaroo and I have downloaded version 2.2.1 and most of the commands show up. However, one of the commands which I am trying to use does not appear and it tells me it is on version .094 but I can't seem to find this anywhere. I tried downloading older version but no luck. Am I setting up kangaroo wrong? Or am I missing something.

The command circled in red is what I am missing... 

Please help!! Thank you!
