I am using megaslider on an Aegir installation and Aegir is not allowing me to upgrade from 7x2.18 to 7x2.19

In the .install file,  the older module has a higher schema version -number 7310 - compared to the newer module's 7300

The old 7x2.18 version is
/**
 * Implement hook_update_N()
 * Update weight module md_slider
 */
function md_slider_update_7310() {
  $success = db_update('system')
              ->fields(array('weight' => 999))
              ->condition('name', 'md_slider', '=')
              ->execute();
  if ($success) {
    return "Update weight module md_slider successful";
  }
}

The new 7x2.19 version is
/**
 * Implement hook_update_N()
 * Update weight module md_slider
 */
function md_slider_update_7300() {
  $success = db_update('system')
              ->fields(array('weight' => 999))
              ->condition('name', 'md_slider', '=')
              ->execute();
  if ($success) {
    return "Update weight module md_slider successful";
  }
}

Is this right?

What should the version be for 7x2.18?

Can you email me a copy of the 7.2.18 module

Thanks,
