[Plugin: Infinite-Scroll] Infinite scroll for RT-Theme 17 Theme

Hi,
I’m using this theme:
http://themeforest.net/item/rttheme-17-responsive-wordpress-theme/2703099

I tried this selector:
– Content Selector: #content left clearfix
– Posts Selector: #content left clearfix .post
– Navigation Selector: #paging_wrapper clearfix
– Next Page Selector: #paging_wrapper clearfix .arrowright

but doesn’t work.

Can you help me to find the right selectors for my theme?
