[Plugin: Issuu Embed] I've missed something – Just paste the URL in??

I have tried pasting the URL in to posts and pages but the Issuu doc doesn’t show up.

The URL’s I tried:
The one in the browser window – http://issuu.com/sweetandmaxwell/docs/jctnewsfeb2012

and the embed URL – http://issuu.com/sweetandmaxwell/docs/jctnewsfeb2012?mode=window&printButtonEnabled=false&shareButtonEnabled=false&searchButtonEnabled=false&backgroundColor=%23222222

Is there anything else I need to do? Do I need a shortcode??

Sorry if this is just rediculously obvious.

Thanks

*EDIT* – What I get is a link to the doc is this correct? I was expecting more of an embedded doc with the option to pop out to full screen.
