Trimble Link won't install in C3D

So we've got Trimble Access on a couple of the data collectors & wanted to give the field crews some flexibilty in having more on their data collectors so they could see a better picture of what they're staking rather than constantly having to plot out paper maps that get destroyed pretty quickly. I saw one of those youtube videos (see below) explaining how Trimble Link was able to become an add-on in Civil 3D and help export Civil 3D entities such as Alignments, Parcels & Feature Lines directly into Trimble Access (or so I thought). However, I've followed the steps in the video & yet the Trimble Link tab won't show up on my ribbon/menubar in C3D. anybody had this issue before? am I missing something obvious?
