JW Player 6 Captions-2 not displaying

My .srt captions file is not displaying in the new jw6 player. Looking at the network trafic I can see that it isn't being called. Not sure what's up. here is the code I'm using which is pretty much lifted from the instructions. I don't see the CC button either.

<div id='my-video'></div>
<script type='text/javascript'>
jwplayer('my-video').setup({
file: 'privacy.mp4',
image: 'privacy.png',
skin: 'skins/stormtrooper.xml',
plugins: {
'captions-2': {
file: 'privacy.srt'
}
},
dock: 'false',
width: '480',
height: '270'
});
</script>

thanks,
Eric
