My program is doing the same thing. I can't work on saved files or start new
ones. However, the computer (and programs on it) were bought from another
company and we do not have the 25 character product key to activate. Will I
have to buy another excel program? or is there a way to get around it?

Trial version period expired perhaps? Or you have not activated the
