Why isn't the animation rigging toolset functioning as it does in the videos?a

I’ve installed the animation rigging toolset, but there are a few issues as opposed to what I’ve seen in video tutorials etc leading me to believe that my install is broken

  • I can’t save out skin weights
  • every time I load up maya the epic games menu disappears unless I’ve freshly copied the scripts in the maya scripts folder
  • I can’t make the proxy mesh disappear through the menu options, I have to manually scale it down so I can see my mesh
