it was set to 666 ...
Seeing as I can't view your site, can you download settings.php and upload it here??
i managed to make it work. i open'd settings.php with notepad and changed the cookies, after i cleared the cookies from FF and uploaded the settings.php again, now it works :d thanks MattR for the point with settings.php
Well all that was in the sticky... anyway, glad it's working.
