I am trying to upgrade my MBX 1.7c to 1.7 Ep. After I back up the system and re initialize the system I go back into programming and press the S/W upgrade button and then press the file upload button or really any of the buttons in the left column and nothing happens. I can go to any other page and the system responds, such as programming and so on but nothing on the software upgrade page. I know I'm missing something but what? Any help would be appreciated.
