After cloning a site using Cloner a plugin is not working

After cloning a site using Cloner a plugin is not working (Use Any Font) on the cloned site. I have asked the developer and my provider and neither can help. Do you have any idea why this plugin would not be working? The site is dmgt802.acdeonline.com.au.

Also, can I buy individual wpmudev plugins or do I have to upgrade?
