I have one NAE 35 with 6 UNT controllers on it. Three times now over the past 1 1/2 years I have had the Date Change from 2007/2008 to 2107 or 2108. This coincidently puts the days off by two. I replaced the NAE once as suggested after re-flashing. A second time Mother Johnson made some changes that were supposed to fix what I had screwed up. Has anyone ever had anything ever happen to them? What did you do to fix it?
