Errror message when starting Excel for Mac 2011
Every time I open Excel I get the following error message. After hitting OK, Excel opens as normal to a blank new sheet, but the error message returns the next time I open Excel. I am opening Excel from the dock icon, not trying to open any specific file.
(BetterHistogram_20070222_2050.xla is a file I opened some time ago but don't even have on my computer anymore)
Does anyone know what's going on or how I can fix this? Thank you for your help.
