Joomla: 1.5.18
JoomSEF: v 3.6.5
PHP Version: 5.2.10
Web Server:  Microsoft-IIS/6.0
Ionics Isapi Rewrite is installed and configured.
I am getting;
 
The page isn't redirecting properly
 
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
 
    *   This problem can sometimes be caused by disabling or refusing to accept
          cookies.
only on the domain root eg. 
www.domain.com/
If I add index.php/ eg. 
www.domain.com/index.php/ the page loads.
If I create a custom url like 
www.domain.com/home the page loads.
My Iirf.ini file contains;
########## Begin - Joomla! core SEF Section

I've tried all three groups without any luck. 
I did have this working with the older, free version of JoomSEF, but not having any luck with the latest paid version, but going back to this version is not an option as I don't want any links on the site.
Although, not  the ideal option, I would settle for it to redirect to 
www.domain.com/home
Please help!!
