dhtmlxLayout 4H,6C etc not working


We have purchased the professional suite and till now were using ‘3’ series of layout and every thing were fine.But recently we have tried to use the additional pattern ‘6c’ and found out that it is not working.so when we checked , certain other layouts like 4H ,4E , 5H are also not working.
Would like to know the solution as soon as possible.Down below the sample code with this.



	<!-- dhtmlxLayout -->
    <link rel="stylesheet" type="text/css" href="./javascripts/dhtmlxLayout/dhtmlxLayout/codebase/dhtmlxlayout.css">
    <link rel="stylesheet" type="text/css" href="./javascripts/dhtmlxLayout/dhtmlxLayout/codebase/skins/dhtmlxlayout_dhx_blue.css">
    <script src="./javascripts/dhtmlxLayout/dhtmlxLayout/codebase/dhtmlxlayout.js"></script>
    <script src="./javascripts/dhtmlxLayout/dhtmlxLayout/codebase/dhtmlxcommon.js"></script>

    <!-- dhtmlxWindows -->
    <link rel="stylesheet" type="text/css" href="./javascripts/dhtmlxLayout/dhtmlxWindows/codebase/dhtmlxwindows.css">
    <link rel="stylesheet" type="text/css" href="./javascripts/dhtmlxLayout/dhtmlxWindows/codebase/skins/dhtmlxwindows_dhx_blue.css">
    <script src="./javascripts/dhtmlxLayout/dhtmlxWindows/codebase/dhtmlxwindows.js"></script>
	<div id="itemLayout"  style="position: relative; top: 20px; left: 20px; width: 600px; height: 400px; aborder: #B5CDE4 1px solid;"></div>
 	var dhxLayout = new dhtmlXLayoutObject("itemLayout", "4E" );


not all patterns are included into the dhtmlxlayout.js. To use “6c” as well as some other patterns you should include additional js file:


I included that 6c pattern js file.again it is not working.
Please help me.The sample code is following…


The code looks correct locally works correctly. Check that dhtmlxlayout_pattern6c.js is correctly included.
