Undefined property: stdClass::$cc_num in ms_core_payment_profile_save

Not sure if anyone is still around, but i could use a hand fixing the following error, which appears post-payment, on the thank you page:

Notice: Undefined property: stdClass::$cc_num in ms_core_payment_profile_save() (line 884 of /code/sites/all/modules/moneysuite/ms_core/ms_core.recurring.inc)

It refers to this line:

$pp->cc_num = ms_core_mask_cc($pp->cc_num);

in this section of code:

function ms_core_payment_profile_save($pp) {
  // Convert to object if it is an array.
  if (is_array($pp)) {
    $pp = (object)$pp;
  }
  
  $pp->cc_num = ms_core_mask_cc($pp->cc_num);

  if (isset($pp->id)) {
    // Update the record.
    drupal_write_record('ms_core_payment_profiles', $pp, 'id');
  } else {
    drupal_write_record('ms_core_payment_profiles', $pp);
  }

  return $pp;
}
