There can be a number of things that can cause this. Wrong software, wrong market code, wrong cable...
Give us some details to work with:
-Full- model number of each radio, photo of the tag on the bottom would be ideal.
-Full- model number/manufacturer of the programming cable
-Full- model number of the software, including version number
And tell us about your computer. Some of this older software isn't going to work no newer machines.
