cannot log on gdm after deleting default.keyring

[jetboo]

hi there, i really need your help, it seems this time i really messed up my gui...
I fallowed this tuto http://ubuntuforums.org/showpost.php?s=f5de5634f4448d733a599c23e4bb0257&p=2776815&postcount=1 because i was bored of the nm-applet keyring-password popup

so i added @include common-pamkeyring at the end of my /etc/pam.d/gdm (as root) and i deleted $HOME/.gnome2/keyrings/default.keyring (as user)
i rebooted and now i cant log on gdm anymore as user or even as root !!

plz help !
