I am using SUSE 9.1 and jreceiver. Some of the issues I found with this was that I had to go into mysqlcc to change the passwords. I went in and had to change the one that was for the server name myself, it seemed that localhost always worked to change, then because that was already encrypted, I copied that password into the one for my server in my case Homer. Open your user table and make sure that you have passwords in for all of the users needed for that machine.

After you changed the xml file for jreceiver were you able to see the tags page correctly?
