You might be better off contacting SCT for this one, depending on which X-3 you have will determine which firmware you will need. There are steps that need to be done after you download the "Device Update Software", they might have you plug in the device to your PC and hold down the select button to update the firmware. Then if you have non-enhanced device, your gonna need the "Tune Revision" software.
It's been awhile since I set-up my PC with the SCT device, to give you a clear answer.
They even can "remote" your PC and do the set-up for you.
