had the same bug and changed the submit.php from:
$download_name=time()."-_MYDWONLOADSPRO_-".$HTTP_POST_FILES['userfile']['name'];
to
$download_name=time()."DL".$HTTP_POST_FILES['userfile']['name'];
$download_name=time()."-_MYDWONLOADSPRO_-".$HTTP_POST_FILES['userfile']['name'];
to
$download_name=time()."DL".$HTTP_POST_FILES['userfile']['name'];
