Have you loaded the proper NEC usb drivers?
You need to actually have installed the USB drivers and detected the device on the computer first. So that when it is plugged in, you should see several devices listed for the phone in the hardware manager. If you have not done this, the program has no way to send data to the phone or retrieve it from the phone.
Have you tried using memory editor software and if so, did it work? fyi l used Personal Information Editor III downloaded free from the aussie nec mobile website.
Look at the thread (below), for some general help on using the ace Nectalk unlocking utilty written by a guy who goes under the name of Stalewind.
