Upgrade to 3.0.0 breaks display

I have been trying to upgrade the FastSpring plugin to the latest version, 3.0.0 from 2.0.2, and when doing so the shortcode stops working on the page. The current plugin I use, 2.0.2, is causing issues with GravityForms not being able to save changes correctly so I have to de-activate the FastSpring plugin everytime I need to make a form change in GravityForms.

The error received when upgrading to FastSpring 3.0.0 that is breaking display is

jquery.min.js?ver=3.3.1:2 jQuery.Deferred exception: Cannot set property 'onclick' of null TypeError: Cannot set property 'onclick' of null
