He's in Christchurch so a bit of a drive (and car ferry!) from you
Also with the tactrix plugged in I don't see any "Port" connection in my devices manager, although I do see "Vehicle PassThru Interface" which has the tactrix 2.0 device.
This is normal. Run learning view and click connect (no com port needed to be selected) and no need for connecting green test leads (which on JDM should be near right foot of front passenger under carpet) for RR logger either. Green leads only for reading/writing rom with ecuflash
Assume you installed *latest* ecuflash which should update latest drivers and (when I ran - I think - ecuflash) it also updated firmware on tactrix connector
