Avid Artist Mix Driver & Firmware Trouble - Please Help!

[Just Another Guy]

I just recently updated from 10.8.5 to 10.11.6 (Mac OSX), and my EU Control advised me to update the firmware for my Artist Mix, but now I get an update firmware message every time I restart the Eucon Applications (I also am now using Eu Control 3.2.2 - is this the wrong driver?)

I am thinking of going to Sierra (Mac OSX 10.12), but I wanted to see if I could get things working properly before I move to Sierra since I would have to use different Mastering Software (Waveburner no longer supported after 10.11.6), which means I would have to buy a new platform, which I wanted to avoid if possible. Please help!!
