Problem Displaying Recent Last.fm Plays

[pealo86]

I'm using the following script on my website, it used to work fine but now it just outputs 'error' from the else statement:

 

<?php
	$username = 'pealo86';
	$scrobbler_url = "http://ws.audioscrobbler.com/2.0/user/" . $username . "/recenttracks";
	 
	$scrobbler_cache_file = 'scrobbler_' . $username . '_data.cache';
	 
	if (file_exists($scrobbler_cache_file)) {
	  if (time() - filemtime($scrobbler_cache_file) > 180) {
	    // if the file was created more than 3 minutes ago then delete.
	    unlink($scrobbler_cache_file);
	  } else {
	    $scrobbler_url = realpath('./' . $scrobbler_cache_file);
	  }
	}
	 
	if ($scrobbler_xml = file_get_contents($scrobbler_url)) {
	    $scrobbler_data = simplexml_load_string($scrobbler_xml);
	 
	  if (!file_exists($scrobbler_cache_file)) {
	    file_put_contents($scrobbler_cache_file, $scrobbler_xml);
	  }
	  
	  // limit to 3 songs
	  $count = 0;
	  echo '<ul id="feed-lastfm">';
	  foreach ($scrobbler_data->track as $track) {
	      if ($count == 3) {
		      break;
		  } else {
			  $string = '<li>';
			  $string .= '<div class="cover">';
			  if ($track->image[1] != '') {
				  $string .= '<a href="' . $track->url . '"><img src="' . $track->image[1] . '" alt="' . $track->album . '" /></a>';
			  }
			  $string .= '</div>';
			  $string .= '<div class="content">';
			  $string .= '<span class="title"><a href="' . $track->url . '"><strong>' . $track->artist . '</strong>: ' . $track->name . '</a></span>';
			  if (!$track->date) {
				  $date = '<span class="highlight-00a2f5 currently-listening">Currently Listening</span>';
			  } else {
				  $date = 'Played: ' .$track->date;
			  }
			  $string .= '<span class="date">' . $date . '</span>';
			  $string .= '</div>';
			  $string .= '</li>';
			  echo $string;
			  $count ++;
		  }
	  }
	  echo '</ul>';
	} else {
	
	echo 'error';
	}
?>

I got the script from here:

Does anyone have any idea what I'm missing?
