Can't access website via cURL from localhost but can from hosted server

I am writing a script that fetches XML data from wowarmory.com using PHP 5 and cURL:

$url = "http://www.wowarmory.com";
$userAgent = 'Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.1.12) Gecko/20080201 Firefox/2.0.0.12';

$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
curl_setopt($ch, CURLOPT_URL,$url);
$str  = "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n";
$str .= "Accept-Language: en-us,en;q=0.5\r\n";
$str .= "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7\r\n";
$str .= "Keep-Alive: 300\r\n";
$str .= "Connection: keep-alive\r\n";
curl_setopt($ch, CURLOPT_HTTPHEADER, array($str));
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_TIMEOUT, 3000);
$xml = curl_exec($ch);

      

        
        
        
      

    

When I run this from my hosted web server, I get an XML response as expected. But when running from my local web server, I get nothing.

I can get any other site via cURL from localhost (yahoo.com, even worldofwarcraft.com) but not wowarmory.com. So I know cURL works fine.

I am using the following PHP and cURL versions:

Hosted Server:

• php 5.2.6
• cURL libcurl / 7.16.1 OpenSSL / 0.9.7e zlib / 1.2.3

Localhost:

• php 5.2.6
• cURL libcurl / 7.16.0 OpenSSL / 0.9.8i zlib / 1.2.3

Any ideas?

EDIT: Localhost is running Windows XP SP3. I can access wowarmory.com through a web browser. Tracert starts timing at jump 13 (from my location, obviously):

I'm not familiar with tcptraceroute unfortunately.

The binary version of curl for windows returns nothing for http://www.wowarmory.com/ but for http://www.yahoo.com/

I don't have wget.

EDIT 2: I can access my locally hosted site. This is just an answer from curl that I am not getting. I am running a fairly standard default XAMPP installation (apache 2 on windows xp). All this is wonderful.
