Regenerate all is non-functional

When someone tries to use "Regenerate all", a database exception appears, because:

$q3 = db_select('maesto_queue_from','a');
$q3->addField('a','from_queue_id');
$q3->condition("a.queue_id = {$active_queue_record->id}");
$queue_reporting_result = $q3->execute();
foreach ($queue_reporting_result as $queue_reporting_record) {
  $record = new stdClass();
  $record->id = $queue_reporting_record->from_queue_id;
  $record->process_id = $new_processid;
  drupal_write_record('maestro_queue',$record);
}

in maestro_engine_version1.class.php, line 160, inside MaestroEngineVersion1::newProcess();
1) It has a typo: "maesto_queue_from" instead of "maesto_queue_from". It raises an exception.
2) The drupal_write_record tries to include the ->id, which is primary key, without specifying that it's an update. It raises an exception (at least in some cases).
