Teranex AV - Update from 6.1 to 7.1.3 not working

G'day All,
Some help please. I have a Teranex AV on Firmware 6.1 and was hoping to update to 7.1.3.
I'm using a macbook pro via USB and have downloaded and installed the latest Teranex Setup program. When I connect to the AV via USB C it says "Your teranex is up to date and ready to use" though it is still on 6.1 FW.
What am I missing?
Thanks Aaron
