Issue between 2 plugins

I have a Wordpress site running that had existing pages with Memphis Docs plugin running happily. I’ve since installed Calendarize It and Memphis Docs no longer works. (I tested by deactivating CI and MD started working again). There is an issue between the plugins. Is there a way to fix this or do I need to sacrifice and deactivate one of them? Any help in non “code-speak” or step by step instructions would be excellent. Thanks heaps!
