Fatal Error on support system plugin for buddpress

I have installed this plugin on a buudypress site. I am aware that it doesnt work on a single site. But does it need to be multisite as well as buddy? Does it not work for just buddy 1.7.2?

I get this error:

Fatal error: Call to undefined function get_blog_details() in /home/demomybo/public_html/wp-content/plugins/incsub-support/admin/pages/admin-single-ticket-menu.php on line 185
