redirect for wp-login.php? Help

My wp-login.php script is directing me to https://www.idowens.com/wordpress/wp-login.php?redirect_to=%2Fwordpress-1.0.2%2Fwp-admin%2Fpost.php when in fact the address should be /wordpress/wp-admin/post.php.
I recently changed my dir in phpmyadmin, but can’t figure out how to change it here on the login page. The first time I login, i get a 404 error…the second time always directs me to the correct page…Any ideas?
