Need technical help: excel crashes when trying to save 4/16/2003

I am hoping someone can help me with this problem. I just upgraded to OS 10.2.5 and now whenever I try to save any changes in excel the program crashes (i.e. unexpectedly quits). Actually, the first time it crashed in the middle of data entry. I use excel frequently and really need to remedy this problem. Can anybody point me to a fix? Thanks!
