Really frustrated ftp install help

I recently did an ftp install of SuSE8.0 to make it faster I had previously downloaded the entire distru on a windows machine shared it then mounted the share n my ftp/pub folder. Install worked no prob. However now I wish to add a few aditional packages. However when I set up the source I get unable to mount source or if could not find file. I then used ftp.suse.com and a few other mirrors same prblem. Then I mounted the smb share localy on my drive /mnt/suse/ and I keep getting unable to mount source - this is with a harddrive install. I'm about to pull my hair out.
