Have not seen any postings on this issue. I'm trying to update my controller software for the first time. I'm using a windows 10 & have installed the correct 340 driver & I can see it when I plug in my programmer cable. I have tried both LUNA & Petroff software & results are same. I can bring up the software & connect to the correct port for my cable. I think I am connected because if I pull the cable out of the computer, I get a quick message that I lost communication with my controller. But here is whats not happening. When I open up the software program * hit connect the 4 boxes at the bottom are not lighting up-----READ/WRITE/READFLASH/WRITE FLASH.... I'm stuck. Yes Battery is on and Connected. Can't figure out why this is happening & been through a ton of Vids & still no answer.
