You're not creating the DOM correctly, you must do it like this:

// Create a DOM object
$dom = new simple_html_dom();
// Load HTML from a string
$dom->load(curl_exec($ch))

print_r( $dom );

Check the Manual for more details...

Edit

It seems that is a cURL settings problem, please refer to the documentation to configure it correctly...

This is a function I usualy use to download some pages, feel free to adjust it to your needs:

function dlPage($href) {

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_HEADER, false);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_URL, $href);
    curl_setopt($curl, CURLOPT_REFERER, $href);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.125 Safari/533.4");
    $str = curl_exec($curl);
    curl_close($curl);

    // Create a DOM object
    $dom = new simple_html_dom();
    // Load HTML from a string
    $dom->load($str);

    return $dom;
    }

$url = 'http://www.example.com/';
$data = dlPage($url);
print_r($data);

Curl will return a string containing the HTML right? Just use the quick start sample?

$html = str_get_html(curl_exec($ch));
