No JavaScript in Text Widget (Adsense Code)

Hello

I use wp 3.1.4 and Atahualpa 3.6.7. My Blog is NOT hostet by WordPress.com

Problem:
I canot add some Adsense Code in the Textwidgets to display in the Sidebar. Wenn i add the code (generated by my google adsense acoount), in the textarea from the widget and klick safe, the “safe-symbol” turns and turns, but my code got never saved. Wenn i insert some text it works.

I also deaktivated all my Plugin’s, but even then, it was not working.

my blog: http://www.kitetheworld.ch

Here the code i insert:
Code:

<script type="text/javascript"><!--
google_ad_client = "pub-xxxxxxxxxxxxxxxx";
/* testadsense */
google_ad_slot = "xxxxxxxxxx";
google_ad_width = 120;
google_ad_height = 90;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

Also when i insert this code in a article (html mode) and click “save”, my browser reports, Error 101, Website not available (Goggle Chrome). I have the same with other Browsers.

I searching around since day’s, but didn’t found a solution.

Maybe someone can help me
Thanks Thomas
