Just updated Mini TT1 & Flex TT5 firmware to 6.150 for Canon Speedlites. Now flashes can't be triggered. When camera is fired Mini TT1 blinks red twice. Have used different combinations of 580 EX and EXII and 600 RT. Have reinstalled firmware in all three TT5 units and changed battery in Mini TT1. Any ideas?
