Comments Plus crashed my site - part II

Hi -- I'm responding to the earlier response (thanks!) to my previous support request as I could see any way to actually respond to that response. In any event, yes, it crashed the site as in, the instant the plugin loaded the site when down--poof--I called WPEngine emergency support and they pointed to a cascade of fatal errors that had been triggered the moment the plugin went live, shutting down the entire site. Is this a new plugin? Thanks again for the response. Sorry to be starting a new thread like this.
