Unfortunately, according to this page:
http://avid.force.com/pkb/articles/f...pport&filter=0
C600 is no longer supported as of February 11, 2018. Sad news for us.
Currently using Windows 10, version 10.0.17134 Build 17134
with the latest Firmware: 0.1.7 and Package: 1.1.7 (which was updated last 2014 for us PC users - unlike Mac users who had an update just before support was ended).
Lately, I've been experiencing random disconnects from the interface. I'll still try to contact Avid Support, and see if there's still anything that can be done.
