Hi Loretta,
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
