[Plugin: AutoChimp] Auto-Convert Embedded Videos not working

I’ve noticed that the auto-convert is not working with my youtube videos in my email campaigns; I’m wondering if it is not adding the video merge tags correctly. It does not add the “picture” to click on to view the video in the email. Is there something that I need to be doing to make this work? I upgraded Autochimp to version 2.15 when it was available.
