New site doesn't remember my user name and password

[Ducatiloo]

When I type in www.ducatimonsterworldwide.org I am auto logged in.
When I type in www.ducatimonsterforum.org it lists me as "guest", even though every time I enter my user id and password I choose forever.
I have tried to clear my cache, cookies etc and stil have the same issue. 
Running xp IE 6.0
