Works fine in WP3.8.2.
Are you sure your theme supports ‘menu’?
I have the same problem. It has to do with the “short_open_tag” configuration setting not being allowed and the script having several instances of it starting on line#87 – line #209. To fix use a text editor and replace all instances of <? with <?php . Make sure you don’t end up with <?phpphp …….. 🙁
btw: the version available on wordpress/plugins is only 0.10.
