FTP download

Hi, I'm new to this mailing list. I defected from Red Hat after they stabbed be in the back. I went out and bought/installed Suse 8.2 professional. One week later 9.0 professional came out. I am having difficulty upgrading from the FTP site. I boot from cd with the boot.iso image just like they say. It seems their instructions are not clear to me. After I put in the installation directory the server keeps telling me the file does not exist. Any way, can someone help me with specific instructions, they know work, on using the SUSE ftp site. Thanks Aaron
