New install of RH5, first time I endeavored in RH5 (used centos 5 with no 
issue). After the install I do the usual rhn_register and use my RedHat network 
credentials to utilize the available entitlements. I get the following error 
after I put in my user name and pass. Mind you, no X, all of this is done 
through the curses interface.

stdout:
An error has occurred:
up2date_client.rhnreg.InvalidDefaultError
See /var/log/up2date for more information
