You get this error message if you have set not to send Private Messages to winners. This was a bug which I fixed in the original file. Here is how to fix it:

admincp/competitionmanager.php

Find:

	if ($vbulletin->options['hkc_send_pm_to_winners'])
	{
		print_textarea_row($vbphrase['hkc_custom_pm_message'], 'custom_message', $vbphrase['hkc_pm_custom_message'], 4, 40, false);
	}

Replace with:

	if ($vbulletin->options['hkc_send_pm_to_winners'])
	{
		print_textarea_row($vbphrase['hkc_custom_pm_message'], 'custom_message', $vbphrase['hkc_pm_custom_message'], 4, 40, false);
	}
	else
	{
		construct_hidden_code('custom_message', 'nothing');
	}
