Hi Melissa,

If you have a boxed retail copy of Microsoft Word or Office you can use the
phone numbers at http://microsoft.com/worldwide (800-360-7561 in the u.s.)
To get a replacement key. If it was pre-installed on the PC when it was
purchased, it's an oem copy of the software and you will have to contact the
pc supplier for a replacement.

Please post any further questions or followup to the newsgroups for the
benefit of others who may be interested.  Unsolicited questions forwarded
directly to me will only be answered on a paid consulting basis.

Hope this helps
