Live Chat Inc (https://www.livechatinc.com/)

Do not state on their website that they support DNN integration but do give a peice of JavaScript in order to display the chat on the page:

<script type="text/javascript">
window.__lc = window.__lc || {};
window.__lc.license = *******;
(function() {
var lc = document.createElement('script'); lc.type = 'text/javascript'; lc.async = true;
lc.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'cdn.livechatinc.com/tracking.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(lc, s);
})();
</script>

I have tried adding this to the Default.aspx page under the body tag and though I can see it in the source code it does not actually display the chat window on the website.
