Fastspring license generation failing with no errorsAnsweredLocked

Hi. At some point over the last few days the Fastspring license generation started failing.  I've read your document as to what to uncomment in the script.   I've changed the acript as follows:

    {

       // Uncomment the next line to see the error LimeLM is giving you.
 echo 'test1';
       echo $jObj->message;
 echo 'test2';

   }
}
catch (Exception $e)
{
   // Uncomment the next line to see the exception.
   echo 'Failure: '.$e->getMessage();
}
 

I'm getting the test1 and test2 output but no message from echo $jObj->message;

Any help would be appreciated
