Problems with Microsoft Word 2000

[Starflash]

On the Web Tools toolbar, when I click on the button to add background sound, I get this message:

"The server application, source file, or item cannot be found.

Make sure the application is properly installed, and that it has not been deleted, moved, or renamed."

I haven't deleted, moved, or renamed anything at all; so I cannot figure out what's going on. I've tried repairing Word, I've tried uninstalling and reinstalling it (countless times) with absolutely no result. Does anyone know what is going on? How do I fix this problem?

This copy of Microsoft Word was originally for my old Windows 98 computer, but when I got a new XP, I decided to install it onto the new computer because I prefer Word over Works (which is what the new computer came with). I used to be able to add background music to my documents on my old computer, but that feature refuses to work on this one. Could it have something to do with the new computer, or is something wrong with the program?

I am so confused...
