Site permissions messed up after creating module, please help

I created a module as pr. http://drupaldojo.com/files/screencasts/drupal-dojo_minilesson8.mov to redo the login procedures. I then created the following module granadalogin with the code:

Code for granadalogin.module

<?php
// $Id$
        /**
         * Implementation of hook_menu().
        */
function granadalogin_menu($may_cache) {
        $items = array();
        if ($may_cache) {
        }

        else {
                $items = array (
                                'path'                  => 'granadalogin/login',
                                'title'                 => t('Log in'),
                                'description'           => t('Ajax callback'),
                                'callback'              => 'granadalogin_login_page',
                                'callback arguments'    => array(),
                                'access'                => $user->uid == 0,
                                'type'                  => MENU_NORMAL_ITEM,
                               );
        }

        return $items;
}

function granadatheme_login_page() {
        print drupal_get_form("user_login");
        exit;
}

?>

contents of granadalogin.info:

; $Id$
name = Granada Login
description = Gives the jquery login link a clean page to access
core = 6.x

After trying to enable this module everything went sour, shutting out my superuser giving access denied error messages everywhere and now I'm stuck, desperatly in search for help. Could anybody help, please?
