It seems the system doesn't support usernames in this format:

xxxx.xxxx

If your username is "john.doe", then http://john.doe.drivehq.com/ doesn't work. So please use a simpler username. You can use it like john-doe or JohnDoe.

 I published my website to www.home but i cant see it.... live

In order to publish and view your website, you must be a true or paid DriveHQ member.  For information about becoming a true or paid member, please see here: http://www.drivehq.com/help/doc/myaccount.htm.  Please also make sure your homepage is titled "home.htm" for it to work properly.
