@myfaction: Sorry to inform you that you may have to edit your theme file to print the buttons. We couldn't try it further as the theme is not in our collection.
You can use
<?php do_action('addthis_widget',$url , $title, $style);?>
$url is the URL you wish to share. Generally, this should be get_permalink() if you are inside of the loop.
$title is the title of the URL you want shared. Generally this should be get_the_title() if you are inside of the loop.
For $style you can use a string 'above' or 'below' to choose the style you have configured for displaying in the AddThis settings.
If you are not comfortable in editing your theme files, I can assist you there.
