Hi Jason,   
  
 Which version of the notification application are you running? Make sure you’re on a recent build by re-downloading the installer from your FinalBuilder Server administration page.   
  
 Please let us know if you still see the same error after updating it.   
  
 Regards,   
 Paul.
