PS doesn't recognize *.bbf Firmware file?

Just downloaded MK4 firmware 6.2.4 and the resultant file in my downloads folder is 'MK4_MK4S_MK3.9_MK3.9S_firmware_6.2.4.bbf'.  When I try to flash this firmware using PS Configure->Flash Printer Firmware, it doesn't recognize the filename.  Am I doing something wrong here?

TIA,

You might try renaming it to something shorter like UPDATE.BBF , then try to flash it.

MK4S/MMU3
