<p>How is possibile when I try to take data in XML API Steam, from <a href="http://steamcommunity.com/id/Askancy?xml=1" rel="nofollow">my account</a> works: 
but if I try to get data from <a href="http://steamcommunity.com/id/Giogio993?xml=1" rel="nofollow">another account</a> doesn't work? </p>

&lt;error&gt;
&lt;![CDATA[ The specified profile could not be found. ]]&gt;
&lt;/error&gt;
&lt;/response&gt;
</code></pre>
