version 2.7 [wpdm-all-packages] search form does not appear

solved. and this is a bug in version 2.7 and 2.7.1

I add this code in the file: wpdm-all-downloads.php the first line:

<script language="JavaScript" type="text/javascript" src="<?php echo plugins_url('download-manager/js/jquery.dataTables.js'); ?>"></script> 
<link rel="stylesheet" href="<?php echo plugins_url('download-manager/css/jquery.dataTables.css'); ?>" type="text/css" media="all" />
<style type="text/css">
#TB_window{
    -moz-box-shadow: 0 0 5px #000;
-webkit-box-shadow: 0 0 5px#000;
box-shadow: 0 0 5px #000;
}
#TB_overlay{
    opacity:0.5;
}
</style>

and this code on the last line
