    Try it again, after the message saying the cable is not licensed to this ECM appears, click OK. Let the 15 sec countdown timer go and STOP!! There will be a new button that appears, it says License ECM (or similar). Click this, it will ask you to confirm, click Ok. Then it will say licensed, try flashing again.

    I just tried it again, went through it three times. I click the License ECM button, it thinks for a few seconds, and then I get the error "There are no free license slots available in the Flashscan cable See menu option Help->Flashscan V2 licensing... for more information." Not sure how that is possible.
