Typekit with Wordpress loads Font Styles/Selectors but not font?

Typekit with Wordpress loads Font Styles/Selectors but not font?

I'm trying to get Typekit to activate for the font, Abril, on my Wordpress.
I have the code in my tag which they tell me to embed:
<script type="text/javascript" src="//use.typekit.net/gir7uqk.js"></script>
<script type="text/javascript">try{Typekit.load();}catch(e){}</script>
Here is the styling on Firebug:

So the script is clearly activating, but the font is not loading, and the
stack reverts to serif.
Yes, everything is published. Is this just a problem with Typekit? I've
tried it with several other fonts to no avail.
Also tried it on a webpage on my local machine with the same results - so
it's not a Wordpress thing.
Any help is appreciated. Thank you.
