If you set the PM Cut-off to 0, then the PM system should not be disabled for a warned user.

Check that your functions_warning.php contains the following code:

if (($vbulletin->options['warn_send_pm_warning']==1 AND $vbulletin->options['warn_pmcutoff']==0) OR ($vbulletin->options['warn_send_pm_warning']==1 AND $vbulletin->options['warn_pmcutoff']!=0 AND $level<$vbulletin->options['warn_pmcutoff']))
	{
		$messageb="";
		$name=$user['username'];
		
		if ($wcomment=='' AND $vbulletin->options['warn_autocomments']==1)
		{
			$wcomment=$warn_type['warn_desc'];
		}
		
		if ($wcomment=='' AND $vbulletin->options['warn_allowalertscomment']==1 AND $alert=='Yes')
		{
			$wcomment=$warn_type['warn_alertcomment'];
		}
