Trouble getting Addon module for Cookies running

I am trying to get the addon module for cookies running.  We run a support
portal site, and from that site we want to be able to click a link then be
redirected over to the CS site, already logged in.   

I tried using the CookieAuthTest.aspx, and my own page from the live site, and
both are throwing this error when it tries to read the cookie.

Any ideas what to try to do?  Server Error in '/forums' Application.
