when in the titan software > DMX settings > no nodes available at all. not a single one not even art net. ( see screenshot )
I can control my fixture via the USB expert console , quite happily switch between Rx & Tx - and i know the dongle works fine as it shows up on my friends laptop.
the one thing that worries me is on my laptop , in the expert console the status messages say "[Titan one DMX Panel 1] Chip configuration checksum error!"
i also noticed that when i connected it to my friends laptop it seemed to find another device "Avolites Titan One Security Key" which my laptop doesn't find.

Titan 7.2 suite - uninstalled re installed
devices completely removed
manually tried the drivers from the trouble shooting.
Any ideas?
