Bok,
I figured the issue with me not logging into the stats.
You have two logins. Not exactly sure how they tie in although both can access the forum.
You have the Login at the Top of the page. If you login into that it will NOT link into the Stats systems.
You have to go to the Main Free-DC page and use the login IN the page, NOT at the top. Only the one IN the page links to the stats system correctly (both stats and stats6).
If you use the top login, the system thinks you are logged in and there is no way to access the other login except to log out or close the browser (assuming you haven't told the site to remember you).
It might be a cookie issue. When I used the top login, I did not see that specific cookie you mentioned. I saw other cookies, but not that one for some reason even I had full access to the forum.
