And I am even later but if you aren't needing to save parameter settings of the 11r in your sessions then I would suggest using the 11r as an interface for another DAW, I have and use PT12.4 on my 10.11.3 2012 mac mini with no problems, but I also run Logic X and Reaper 5 with absolutely no issues whatsoever. I realize that on a PC Logic is not an option, but I would highly recommend checking out Reaper, it is free to use with no restrictions (with the expectation that if you like it you pay for it), so it costs nothing to demo!
