Errors on initialization

I am getting started with DataTables and Firebug is not happy.
It is giving me error on the plug in file which is very odd.

Type Error - oCol is undefined on line 820 of the js/jquery.dataTables.js file

 	oCol.fnSetData( oData, val ); 

I include the full initialization code within the head section of my page:

<script type="text/javascript" src="jquery/jquery-1.7.2.js"></script>
<script type="text/javascript" charset="utf-8" src="DataTables/media/js/jquery.dataTables.js"></script>
<script>
$(document).ready(function() {
    $("#myTable").dataTable();
});
</script> 

Anybody has a clue?
