Can't uninstall or repair Office 2003 under XP SP2

Everytime I start Outlook 2003 I get an error message saying Microsoft
Office Word 11.0 - An error has occurred and this feature is no longer
functioning properly. Please run Setup and select "Repair" to restore this
application.

When I do this I get the message that the feature you are trying to use is
on a netwrok resource that is unavailable. It's looking for C:\Program
Files\OfficeUpdate11\Cabs\511735 with installation package
511735.MAINSP1op.msp. This file is not on my hard drive or on the Office
2003 CD.

I cannot repair the problem or remove the Office 2003 and start over for the
Remove also asks for the 511735 file! Office Outlook operates but I cannot
receive and mail. Send/Receive goes through the motions and I believe
actually downloads the mail from my ISP but is not put in any mailbox!

P4 3.0 XP SP2, 1 Gig RAM

I need to repair or uninstall Office 2003. I need help getting out of this
issue. TIA.
