beta2 office2003 re-install

[tom]

I ran the Windows Installer Clean-Up tool and it has
deleted my Beta2 Office 2003 and Office 2000 Professional
programs. Both progrmas have also disappeared from the
ADD/REMOVE Programs. (Windows2000Prof.)

Also if I try to re-install with the BetaOfffice 2003 CD I
get an error message saying the product key I entered is
wrong..although it does not allow me to enter my key#

any suggestions much appreciated.......
