I had this problem with max2016 too. It was like nightmare, on every other launch max would load with default settings. I don't recall if i find some definite solution, i think this behaviour gradually became less and less frequent with time and now it happens very rarely. One thing i noticed that max2016 especially prone to reseting settings when there's multple instances launched simultaneously. Now i try to use one max instance at the time as much as possible, maybe that is why it started to behave acceptably? :]
