Re: My product key won't work, what should I do?

You should uninstall the trial version before you install the version you bought. See http://support.microsoft.com/?kbid=836178 "You receive an 'invalid product key' error message when you start an Office 2003 program after you install Office Professional Edition 2003" for more information.
