LG2-3G tool problems

I am trying to unlock an LG phone and keep getting the following error:
LG 2-3G Tool v9.51
supported models: 1556

Reading timeout, check cable
Error Code: ReadInfo,1,1
Elapsed: 3 secs. --> (v9.51)

The cable is an LG cable and is plugged into my Z3X box. Everything else works fine on the box but I have just started having troubles with the LG portion of the box. :confused:

Any and all help would be most appreciated. I thank all of you in advance.
