I just installed the Live Support component, and I am having trouble with logging into the Live Support Operator.  I just executed the script to create the database.  I entered the default credentials (admin / admin) to login and I am getting an exception that says "Failed to connect chat service: The remote server returned an error (401) unauthorized."  I have set the sample project as the default home directory in my IIS, so my website url should just simply point to http://localhost.  What am I doing wrong?  Please help.
