CANNOT UPDATE WINDOWS! HELP!

I formatted my computer a few weeks ago, and my Windows 2000 CD comes with
Service Pack 3. As i was downloading the updates, i think something went
wrong. Now, when i go to the Windows Update Site, after it checks for the
latest version of the Windows Update Software, i get :

Windows Update Error

How can i get the Updates to work again?

Thank you,
Joe
