So no ****, there I was: trying to get my MAF tuned again today, right? I go and plug some stuff into the MAF Worksheet that I have saved, right? That's when I noticed the Old and New Data were identical. I went to the Calculations tab and saw that the cells had no values in them, they had odd characters in them. What all this means to me is that my copy is corrupt. Does anyone have a copy that I can snag OR the link where I can d/l a fresh copy? Thanks, yall.
