Warning: TableTools 2 requires DataTables 1.9.0 or newer on Internet Explorer (8/9)

Hello,
I'm receiving the error shown below on IE8/9, while the same code works just fine on FF/Chrome:
"
Warning: TableTools 2 requires DataTables 1.9.0 or newer -
www.datatables.net/download
"
Below are the version of the DataTables files I'm using:
dataTables.editor.min.js: 1.2.2
dataTables.tabletools.min.js (code starts with ' var ZeroClipboard_TableTools={version:"1.0.4-TableTools2" ...')
jquery.dataTables.min.js 1.9.4
jQuery v1.8.2


By looking into the Google Chrome Frame, I can see the following errors being triggered:
SCRIPT5007: Unable to set value of the property 'TableTools': object is null or undefined
dataTables.tabletools.min.js, line 57 character 378
SCRIPT445: Object doesn't support this action
table.aqua_cert_progress.js, line 11 character 2

Where code for the referred .js file looks like:

/*
 * Editor client script for DB table aqua_cert_progress
 * Automatically generated by http://editor.datatables.net/generator
 */

	
(function($){

$(document).ready(function() {
	var editor = new $.fn.dataTable.Editor( {                /*Line 11*/
		"ajaxUrl":
