Star Plugins

I am thinking about buying StarZoom but need to get the API to work first.  Trying to make a new StarZoom instance fails:

$(function(){

var options = {"image":"zoomify/images/Banyoles_Olympic_Hotel"};

var myInstance = new StarZoom($('#viewport'), options);

});

With the following errors:

[Error] TypeError: 'undefined' is not an object (evaluating 'a.length')

 $a (undefined, line 1)

 success

 fire (jquery.js, line 3100)

 fireWith (jquery.js, line 3212)

 done (jquery.js, line 9311)

 callback (jquery.js, line 9721)

[Error] TypeError: 'null' is not an object (evaluating 'e.ma.update')

 a (undefined, line 1)

$('#viewport').StarZoom(options) works fine with the same options.
