My apologies, I have paid for a commercial licence, and I need to remove the logo from my player.

Thanks in advance, I am a noob and not java savvy, so please, try and use layman terms...
I have inserted a script on my page, but it makes the player vanish...

<script language="JavaScript">

flowplayer("player", "/swf/flowplayer.commercial-3.1.4.swf", {
// product key from your account
key: 'xxxxxxxxxxxxxxxxx'
});
</script>

My licence is 3.1.3 but I needed to download 3.1.4 as it was an IE patch. That wont mess it up will it?
