I have been getting Microsoft Office Error messages (#1311) when I try to open Excel. I first got these messages earlier today when attempting to set up my Microsoft Outlook software. I have Microsoft Office for Small Businesses 2003. I noticed on some other posts in regards to Error 1311 that inserting the CD helped. However, I no longer have my installation CDs. Is there anything else I can do to access Excel? All the other Microsoft programs seem to be working fine.
