It shows up as though it's completely unlicensed. If you try and do anything useful with it, it pops up a dialog offering either a free trial (doesn't work), Insert my license key (either network error or license expired) or Purchase Navigation (Server connection failed)

I am increasingly of the opinion that the 3 year license length is started from when Navicore was purchased, not from when it was converted from Navicore to Wayfinder. I bought Navicore as soon after it was announced, that would be about three years ago, so the timescale fits

I've dropped them a mail just in case, but I'm not really hopeful of it even being answered.
