howto use the Google Translate API v2

[Oddacon Ripper]

i have the google translate API v1 and I was wondering how do i use the v2.  like do i have to completely my scripts to detect the languages?  like for instance with v1 i use something like:


<script type="text/javascript">

    google.load("language", "1");

    function Translate() {
        document.getElementById('language').style.display = "none";
        TranslateDiv('content');
    }


    function TranslateDiv(div_id) {
        google.language.translate(document.getElementById(div_id).innerHTML, '', document.getElementById('language').value, function(result) {
            if (result.translation) {
                document.getElementById(div_id).innerHTML = result.translation;
            }
        });
    }
</script>

I'm just wondering how i enable the v2 to get it to work.  Do i have to change my scripts?  or do i have to enable billing on the API console page?  please help!!!!!!!!!!!!!!!!!!!!!!!!!!!
