Displaying name in author.php

I’ve been trying to get my name displayed on my author page at http://nerdnirvana.org/author/administrator/, but for some reason, it’s not happening. I am the administrator, and I’ve edited my profile at /wp-admin/profile.php, but it’s still saying “‘s Profile” when I go to my author page.

Here’s what it looks like when I try to edit my profile: http://img292.imageshack.us/img292/4311/editprofileap9.png

Here’s the code that I’m using the display “‘s Profile”: <?php echo $curauth->user_nicename; ?>'s Profile

Of course, before that, I have:

<?php
	if(get_query_var('author_name')) :
		$curauth = get_userdatabylogin(get_query_var('author_name'));
	else :
		$curauth = get_userdata(get_query_var('author'));
	endif;
?>

It works fine for any other authors, but ‘admin’
