Can't log in to Admin after new install

[ProudCDN]

Could someone please help...when I go to localhost/joomla/administrator I receive:

Notice: Undefined property: LoginController::$input in C:\xampp\htdocs\Joomla\administrator\components\com_login\controller.php on line 38

Fatal error: Call to a member function set() on a non-object in C:\xampp\htdocs\Joomla\administrator\components\com_login\controller.php on line 38

Here are lines 32 to 42:

public function display($cachable = false, $urlparams = false)
{
// Special treatment is required for this component, as this view may be called
// after a session timeout. We must reset the view and layout prior to display
// otherwise an error will occur.

$this->input->set('view', 'login');
$this->input->set('layout', 'default');

parent::display();
}

Have a look at cli/deletefiles.php. It removes all outdated stuff. It is executed after updating Joomla the normal way. It makes sure the new stuff is used instead of the old stuff.
