WP3.0 Installation - Editting My .htaccess

I followed all of the 5 step and successfully updated my web site. My only concern is with Step #5. I edited my .htaccess
To:
RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]
But I am still getting this message on the admin panel.

The wp-content/blogs.php file is deprecated. Please remove it and update your server rewrite rules to use wp-includes/ms-files.php instead.

Did I edit the .htaccess correctly?
