[Help] Setting up featured image with WPRobot

I need some help here with setting up featured image with WProbot. My theme support featured image and change /uploads directory to "0777" . Also set the WPRobot to save the image to the server. Still I'm not getting featured image in every post it fetches. I'm using RSS feeds.

check on the bottom of wp robot campaign setup page, you will find a check box to turn on featured image feature.

Already did this, and even tried some auto featured image plugins but result was the same.
