SMARTCRAWL Missing underscore-macros-list.php file after update

After trying to update SMARTCRAWL today, Im getting the following error:

Fatal error: Only variables can be passed by reference in /data/54/4/12/129/4501944/user/5337610/htdocs/wp-content/plugins/wpmu-dev-seo/includes/admin/templates/underscore-macros-list.php on line 5

Upon going into the root files, that .php file is not in the directory. Attempting to navigate to anywhere in the dashboard triggers this error, rendering the entire backend useless. Please advise on the best way to resolve this.

Thanks in advance!
