Plugin missing message even after instalation

Hi, I’m trying to load my unity game into Html using this simple code in the :

<script src='http://webplayer.unity3d.com/download_webplayer-3.x/3.0/uo/UnityObject2.js'></script>

<script>
    var u = new UnityObject2();
    u.initPlugin(jQuery("#unityPlayer")[0], "_Compiled.unity3d");
</script>

And then, this code in the :

<div id="unityPlayer">
	<div class="missing">
		<a href="http://unity3d.com/webplayer/" title="Unity Web Player. Install now!">
			<img alt="Unity Web Player. Install now!" src="http://webplayer.unity3d.com/installation/getunity.png" width="193" height="63" />
		</a>
	</div>
</div>

Howehever, it keeps showing me the button to download the plugin. But the plugin was already installed and on the latest version as it showing in my browser (Google Chrome).
Unity Player - Version: 4.1.2.67171
Unity Player 4.1.2f1

I tried updating the plugin again, but it’s still not working.

This started after I changed my code to the UnityObject2 standards, because even now, if I use UnityObject, it works fine…

What can I do?

Thanks.

For anyone with the same problem, I fixed this by using the full code in the html that Unity generates.
Then I configured the code and removed what I didn’t want.
