1900 pro firmware upgrade Hi there  I tried to run the firmware upgrade  last night but was unsuccessful . I got a message stating that the firmware image failed the security check. Is there a setting on the player that I need to change in order for this to work or is the image file not digitally signed? Please see the firmware version that I tried to install . http://mygicasupport.com/index.php?/files/file/17-1900-pro-jan-30-2017/       Any help would be a
