Trouble parsing my XML Feed

Experts,
For the last few years, I've purchased baseball scores and insert them into my database.  I wrote a script (with the help from some EE members) to do this automatically every day.  This has worked great for 3 years.
Here is the XML of last night's baseball scores:  http://www.officepickem.com/rftwscores/xml/BaseballScores10-2-15.xml

As of October 1st, the company where I purchase the feeds from updated their infrastructure and my scripts can no longer read the feeds.  I can't figure out what changed.

I'm now getting this error every day:  Invalid argument supplied for foreach()

Any ideas?

$xml = "http://www.officepickem.com/rftwscores/xml/BaseballScores10-2-15.xml";
$obj = SimpleXML_Load_File($xml);

foreach ($obj->{"sports-content"}->schedule->{"sports-event"} as $game_data)
{
 
// GET ISO8601-FORMAT DATE ( == MySQL DATETIME )
   $date_time = $game_data->{"event-metadata"}["start-date-time"];
 
// CLEAR ARRAYS FOR CONTEST DATA
   $team_name    = array();
   $team_score   = array();
   $team_decided = array();
   $team_key 	 = array();

   foreach ($game_data->team as $thing)
   {
      $team_name[]    = $thing->{"team-metadata"}->name["first"] . ' ' . $thing->{"team-metadata"}->name["last"];
      $team_key[] 	  = $thing->{"team-metadata"}["team-key"];
	  $team_score[]   = $thing->{"team-stats"}["score"];
      $team_decided[] = $thing->{"team-stats"}["event-outcome"];
   }
