[Plugin: Contextual Related Posts] Warning Error

I get the following error appear at the top of my posts since the latest upgrade as of today:

Warning: Missing argument 1 for ald_crp(), called in /home/xxxx/public_html/wp-content/plugins/contextual-related-posts/contextual-related-posts.php on line 169 and defined in /home/xxxxx/public_html/wp-content/plugins/contextual-related-posts/contextual-related-posts.php on line 44

This plugin has been awesome so far, what could be going wrong here ??
