Yum/Up2Date - No more updates

[Diahron Grismore]

As with everyone else yesterday I cratered my system as well with the 
xorg update. However, I freshly reinstalled FC3T3 from the original .541 
Kernels. Here is my problem, I updated: up2date - gnomeup2date and yum 
at the same time, before attempting to more current updates on other 
files. After. when I run up2date or yum, I get:
An HTTP error occurred:
URL: 
http://fedora.redhat.com/download/up2date-mirrors/fedora-core-3/headers/header.info
Status Code: 404
Error Message: Not Found
ok, what all did I hose doing this? and what do I need to do to repair 
it. I did almost the identical type of update just a few days ago and 
had no problem (that was related to how I updated programs). The Redhat 
Update Alert Icon tooltip reads "No updates available (0) ignored"  If 
you click on it you get an error message.
