Hello,
Make sure you load the software first and then plug in the programming cable into one of the usb ports and see if the software loads first. Afer that you should be able to right click on the My Computer Icon on the disktop and go to properites and then go to the device manager tab. In the list you should see see a + sign next to the com ports listed in the list, click on it and it should be in the list under the other com ports there. If it is a usb cable that you have (mine is) it shold be higher in number than com port 1 (mine is com5)
If you have any questions or need more help please feel free to contact me with a PM.
Take care and good luck!!
Joey
