That sounds like a media error. If you're trying to open it directly from a
diskette, CD ROM, etc., try copying it to the hard drive (Desktop, My
Documents, wherever). Open from there.
Some possibilities. See if you can copy the file to another folder. If it
isn't readable, that will fail. Depending on your version of Excel, you may
be able to click the dropdown arrow in the Open button in File - Open, and
select Open and repair. Send the file to someone else who has Excel (maybe
a later version than you have) and see if they can open it.
I get the same message even when trying to open a document from my hard drive
as well. I have tried to reload my office and that did not work either.
