Is this for live or test drive ?

If it is for live mode, you might want to check: http://wiki.civicrm.org/confluence/display/CRMDOC/Configuring+Front-end+Contact+Dashboard+in+Joomla%21+Sites

2. Modify your index.php file to support CiviCRM front-end functionality

I was getting the exact same thing.  I found a solution at

http://forum.civicrm.org/index.php/topic,1417.0.html that said to do step 3 at http://wiki.civicrm.org/confluence/display/CRMDOC/Configuring+Front-end+Profile+Listings+and+Forms+in+Joomla%21+Sites

So I did and it seems to have fixed things.  What I did was edit index.php:

 Change from:

// mainframe is an API workhorse, lots of 'core' interaction routines
$mainframe = new mosMainFrame( $database, $option, '..', true );

 Change to:

 // These lines are needed for proper function of CiviCRM at the frontend
session_name( md5( $mosConfig_live_site . '_frontend' ));
session_start();

// mainframe is an API workhorse, lots of 'core' interaction routines
$mainframe = new mosMainFrame( $database, $option, '..', true );
