In that case I suggest you remove the remote sources using the GUI tool or
Code:
urpmi.removemedia updates
urpmi.removemedia main
urpmi.removemedia contrib
urpmi.removemedia plf
Then use the easyurpmi page to select a mirror in your part of the world and show you the appropriate urpmi.addmedia commands. You can copy/paste those commands into a Konsole logged in as root.
These are just links to ftp sites. You may want to visit these ftp sites using a browser first to confirm the directories and files are still there, although easyurpmi seems to be kept up to date.
What part of the world are you in? I know of companies in the UK that will put any distro you want on CD and mail it to you for a very small fee. Your local Linux User Group very probably has copies of all the major distributions too.
