Found the problem... I uppercased the username and it worked just fine along with the password being uppercased. I'll see if this translates to the install on the Fire TV.

What do you mean by "you uppercased the username"? Did you change your username and password on the RT web site so that it's all uppercase, did you change your username and password in the addon to make them all uppercase, even though your username/password on the RT web site aren't all uppercase, did you change the username/password directly in the settings.xml file so they reflect the proper case or make them all uppercase?

My username on the RT web site is a mix of uppercase and lower case and my password a mix of lower, upper cases and special characters and entering the username/password directly in the settings.xml file as they are on the RT web site doesn't work.
