Either you have not activated your Office software, or you have an expired
trial version of Office 2003. What happens if you start Word and click on
Help | Activate Product? If you have already activated, a dialog box saying
so will appear; if you are not activated, the Activation Wizard will start.
If you have an expired trial version, a conversion dialog box will appear;
see http://www.microsoft.com/office/trial/convert.mspx for more information.
