Looking for Wordpress Chat Lite

Hi Support,

I have a production website that is a multi-site WP setup and a single WP install (test site) that i use to play around with.

On the single site I have a "wordpress chat lite" plugin installed from the WPMU dev plugin but I can't find this on the multi-site.

Is there some magic plugin access tool that I can't find or is it only for single WP installs ?

Your help appreciated,
