vxr-1000v reads programing but won't write

I'm using a VXR-1000v on a Kenwood tk-7180. I need to change the frequency in the vertex to a new frequency. The CE-22 software will allow me to read the 1000 but it won't let me change the programing. I get the error "Problem detected with connection to interface box". Does anyone have any ideas? I have about 6 of these to reprogram and I have the same problem on the 2 I've tried.
