Office XP Clip Art Error 0x80004002

I am running Office XP Standard for Students and Teachers on Win98se. When I try to open the clip art in any Office XP application, I recieve this message:

Clip Organizer cannot complete the operation.

No such interface supported
Error Code 0x80004002

I ran the reinstall program for Office XP from the add/remove programs icon in the control panel, restarted windows, and I am still receiving the error message. What can I do short of reinstalling the OS to fix the problem?
