find the following code in download-manager.php (roughly line 214):
$html = "<div id='wpdm_file_{$id}' class='wpdm_file $template'>{$title}<div class='cont'>{$desc}{$password_field}<div class='btn_outer'><div class='btn_outer_c' style='{$bg}'><a class='btn_left $classrel $hc' rel='{$id}' title='{$data['title']}' href='$url' >$link_label</a>";
if($data['show_counter']!=0)
$html .= "<span class='btn_right counter'>$data[download_count] downloads</span>";
else
$html .= "<span class='btn_right'> </span>";
$html .= "</div></div><div class='clear'></div></div></div>";
and replace with:
$html = "<div id='wpdm_file_{$id}' class='wpdm_file $template'>{$title}<div class='cont'>{$desc}{$password_field}<a class='btn_left $classrel $hc' rel='{$id}' title='{$data['title']}' href='$url' ><div class='btn_outer'><div class='btn_outer_c' style='{$bg}'>$link_label";
if($data['show_counter']!=0)
$html .= "<span class='btn_right counter'>$data[download_count] downloads</span>";
else
$html .= "<span class='btn_right'> </span>";
$html .= "</div></div></a><div class='clear'></div></div></div>";
