Did you edit announce.php and change the required details?
PHP Code:
////////////////// GLOBAL VARIABLES ////////////////////////////
$TBDEV['baseurl'] = 'http://localhost/TB_ALPHA/';
$TBDEV['announce_interval'] = 60 * 30;
$TBDEV['user_ratios'] = 0;
$TBDEV['connectable_check'] = 0;
define ('UC_VIP', 2);
// DB setup
$TBDEV['mysql_host'] = "localhost";
$TBDEV['mysql_user'] = "root";
$TBDEV['mysql_pass'] = "blank";
$TBDEV['mysql_db'] = "tb";
