Seems I just can't complete the last step in upgrading my REV13A version 4.2 TIU. Wanted to practice on the 13A before doing my REV Ls. I've got Barry's book in front of me and have read and watched whatever else I could find on line. I downloaded the 5.0 Consumer loader. Downloaded the 6.1 upgrade. Relatively new Windows 10 computer. TIU is in program mode with the stereo cable inserted. Serial port to computer with USB. Driver installed. TIU power applied after the stereo cable and then TIU to computer connection made. I followed the prompts accurately ( I think ). Problem is when I get to the last step where I am supposed to find the 6.1 download and I click on it, I keep getting the unzip with Winzip box. It's unzipped but I just can't get past this step. I never get to the screen where it shows the upgrade taking place.Sure looks easy when I watch the videos but I must be doing something wrong. Thought I would try the Forum so I could learn to do this myself. After two nights of frustration trying and thinking about this, I'm hoping someone can help cure my insomnia.
