Try this (worked on my board):
Open the plugin "Usercountdown - Save Settings" and replace the complete contents with this:

  $vbulletin->input->clean_array_gpc('p', array( "countdownuserfield" => TYPE_STR,
                                                 "cdsettings"         => TYPE_ARRAY ));

  $cdsettings     = $vbulletin->GPC["cdsettings"];
  $cdprofilefield = $vbulletin->GPC["countdownuserfield"];

  $cddata["enabled"] = $cdsettings[$cdprofilefield . "_enable"];
  $cddata["day"]     = $cdsettings[$cdprofilefield . "_day"];
  $cddata["month"]   = $cdsettings[$cdprofilefield . "_month"];
  $cddata["year"]    = $cdsettings[$cdprofilefield . "_year"];
  $cddata["hour"]    = $cdsettings[$cdprofilefield . "_hour"];
  $cddata["minute"]  = $cdsettings[$cdprofilefield . "_minute"];
  $cddata["event"]   = $cdsettings[$cdprofilefield . "_event"];
  $cddata["overmsg"] = $cdsettings[$cdprofilefield . "_overmsg"];

  $vbuserfields[$cdprofilefield] = serialize( $cddata );
  $vbuserfields[$cdprofilefield . "_set"] = "1";
  $vbuserfields[$cdprofilefield . "_opt"] = "";

  $userdata->set_userfields( $vbuserfields );

The cleanup script is almost done....
