Just received kit. Installed cables. I keep getting failed between JIB and PC. Green lite on steady, red lite flashing. If there is a lite in the serial to USB cable, it is not lit. I purchased new cables in case that was the problem, no success. I tried two different laptops. I am using the correct com port. What gives. Could it be a malfunctioning JIB? Am very disappointed since I hoped to be using the system today!
