Hi Starry Sky,

I'm sorry your having a problem with Ubuntu, unfortunately this isn't the
proper place to seek help. This list is for discussion between members of
the Ubuntu Bug Squad, not for supporting users who are experiencing
difficulties. A better place to seek help would be
AskUbuntu<http://askubuntu.com/>or the
Ubuntu forums <http://ubuntuforums.org/>.

Good luck resolving your issue, and sorry we couldn;t be of more help here.

Regards,
Chris
