PHP Snoopy 2.0 Not Retrieving Content

I am using snoopy to retrieve the content of a web site and it is not working.
Here is a break down of what I am doing.
1. Retrieving the url's on a specified page.
2. Retrieving the content of those pages.

Here is my code so far. It should be giving me a list of url's but the out put is empty. It seems to be retrieving nothing.

include "include/Snoopy.class.php";
$snoopy = new Snoopy;

// remote url
$url = "http://www.coolcitytrading.com";

// create an array of url's for categories
$cat = array("rc-toys/drones", "r-c-drones/small-size", "rc-toys/drones/medium/", "r-c-drones/large-size-drones", "r-c-drones/drones-with-camera",
"rc-toys/drones/fpv-camera/", "rc-toys/drones/wifi-camera/", "rc-toys/helicopters", "rc-toys/vehicles", "rc-toys/tanks", "general-toys/");


foreach ($cat as $value) {
if($snoopy->fetchlinks($url . "/" . $value)){
echo "<PRE>".htmlspecialchars($snoopy->results)."</PRE>\n";
}
else
echo "error fetching document: ".$snoopy->error."\n";
exit;
}

 

There is a pop-up window on those category pages. Does that prevent the result?

 

I am not sure. Although I can retrieve the page with curl. Is there a way to block the pop up?
