I've been using Office 2008 for Mac with no problems until today. Tried to open an Excel file and immediately get the message "Not enough memory." I don't understand this message, of course. It's a small file and I have 120GB on the hard drive of my 3-month-old MacBook Pro, and 8GB of RAM. I did just upgrade the RAM from 4 to 8 about a week ago, but the system profile reports OK for both DIMMs. Also found that Adobe InDesign crashed on opening. Help!
