How to stop a popup window on my Microsoft Office 2003

[sidb401]

When I try and open a word document on Microsoft Office 2003 work, I get a error saying that I have to close a dialog box. How do I stop this error window appearing before it will open my document.

is that all the error box says? just close dialog box? maybe disable any add-ons you have, or uninstall and re-install office 2003.
make sure you have the compatibility pack installed for office 2003-2007 as well. if you are opening newer versions of word docs in older office 2003 it may cause conflicts.
