Hello group.  Has anyone who had installed the prior 3.o update to their DKC850 tried out this newer update yet?  I'm curious before I proceed to see if there have been any problems or if the 3.1 undoes any of the 850 features gained as the 3.0 update was not officially supposed to be used on the 850 units, just the E3 controllers.
