Unable to display content error message

I am getting this error message on my Windows XP Professional SP 3 machine. Not sure what it means.
I am trying to log into my Logitech Harmony 670 , I give in my credentials and then login. When I click on Next there is an error message which pops up:
Unable to display content. Click Next to continue
I am using Harmony 670 and once I click on next it comes back again to the login screen again. I have the latest download package installed. I have tried it on other MAC machine also and it comes up with the same error message.
