I forgot my login url!
Either go to your MySQL database and look for the value of rwl_page in the options table, or remove the rename-wp-login folder from your plugins folder, log in through wp-login.php and reinstall the plugin.
On a multisite install the rwl_page option will be in the sitemeta table, if there is no such option in the options table.
