I have a microtest Pentascanner. It has stopped finding the injector and has corrupt firmware. I have downloaded the latest software update from Fluke, but it will will not update. When I run the software (as Fluke recomend) It finds the Pentascanner and then displays a message "unable to open flash image file". Fluke do not support this equipment any more, and will not help in any way. Has anyone come accross this with a re-flash on the Pentascanner before? Thanks. Dan.
