Sudden need for FooterData in Grids

Has anyone else had a sudden problem where they are unable to use Advanced Grids because the FooterData property is acting up? We've been using these Grids for a few months now. Not only has there never been a problem, I've never had a to-do list item for a lack of FooterData. I did a quick search and found that I should just need to uncheck the box for the EnableFooter property. Unfortunately, I can't even find that. Does anyone have any suggestions?
