Muziekschuur is right - it's always best to run PT as 'administrator.' Even though - at times - not doing so results in successful sessions - you might experience a sudden freeze or crash anyway. And it always occurs at the worst possible time.
Looking at your ProTools settings, it's difficult to determine if you've enabled USB3 for MTCode. Usually, you'll get a 'Predefined' option in those boxes, then you have to click on that option to see the various USB choices. So, if you're experiencing time code problems, that's likely the problem.
Also, as I've said before: you won't be able to use this setup with the DM's Automated mix option. For that, you need to set the DM as Timecode master, using the MTC Internal MMC, and setting Automated Mix to sync to that with that box ticked in the Autmo-mix setup menu.
