Deprecated error after update

Hi,

I’ve updated the plugin from version 2.1.1 to 2.7.1 but ran into an deprecated error:

Notice: gdrts_method::please_wait is deprecated since version 2.4! Use instead gdrts_loop()->please_wait(). in /usr/www/users/dev/dev/wp-includes/functions.php on line 4648

I’m using this in my template to get the gd rating infos:
$ratingsr = gdrts_render_rating(array(‘echo’ => false, ‘entity’ => ‘posts’, ‘name’ => ‘page’, ‘id’ => $post->ID), array(‘template’ => ‘light’, ‘style_size’ => 20));

Which triggers that error. If I use another template as “light” it works fine.
