For a new page there is no author set in the page attributes.
Try this:

$FmtPV['$Creator'] = 'PageCreationAuthor($pagename)';
function PageCreationAuthor($pagename) {
   $page = RetrieveAuthPage($pagename, 'read', true);
   foreach($page as $key => $value)
      if (strstr($key,'author'))
         $authors[$key] = $value;
   if (is_array($authors))
      return end($authors);
   else return '';
}

or perhaps the last line could also be

   else return '{$Author}';
