I have only had my studio 68c since May. I started the Universal Control App today and it notified me of a firmware update to install which I started, I thought it was the newest,and did not disconnect the box or do anything while it was updating., but about halfway through it suddenly showed a dialog box, about stopped connection. When I tried to start PRO TOOLS afterwards it doesn't connect and the interface only has one blue light on.. I am using MAC OSX 10.15.6 I tried to send a support request but it seems not to send... No email confirmation either. I am in the middle of a paid session so this is down time now... :-( In Sweden so I don't know where to turn.
UPDATE ---- after a number of restarts I restarted the mac and got universal control working right and started all over again and I was able to install the "old" firmware update.... Now everything is working... PHEW...
