Infinite Scroll not working for Paragrams theme

The plugin “Infinite Scroll” is not working on my website which uses the Paragrams theme from Wpshower. I’m running WordPress version 3.8.1 with Infinite Scrolls version 2.6.2.

I found this thread from 1 year ago about setting up Infinite Scroll on Paragrams, where the users were able to make it work: http://wordpress.org/support/topic/plugin-infinite-scroll-not-working-2?replies=24 However, after updates and everything, these instructions no longer work.

Can someone please help me get Infinite Scroll working on Paragrams? Thanks everyone!
