Upon having my 3rd harddrive crash in 6 months, I reinstalled microsoft
office 2003 to another computer (using up my allotted number of installation
registrations). After using Excel for some three years now, it suddenly will
not allow me to enter data into any cells, edit or change worksheets in any
way. I cannot even copy the sheets to transfer to Microsoft Works (if that
is even possible). These are business files. Please help!
