YouTube Video Slider

I’m going to toss this in to see if I can get a bite, or response to an issue I can’t seem to wrap my head around with the revolution slider. I tried to get help over at the themepunch forums and couldn’t get anywhere unless I purchase a new license so they referred me back to the theme owner.
Annoyed:
I buy too many themes with Revolution slider bundled and see no reason why i should have to purchase a separate license. Be nice if said theme owner could provide purchase codes in the themes so that when an issue like this occurs I could just provide the code to get the needed support.

Basically, I have one of the sliders downloaded from the exchange and I’m trying to get it to display youtube slides:

I have it on a site here that’s running Kleo, http://cancerbu.org. I’ve created a YouTube API key and have applied it but can’t get anything to display.

Anyone care to take a “stab” at this one?
Any responses appreciated
