Im still struggling to get goldtree to work!

In goldleaf it says USB was detected, waiting for pc client.
In goldtree it never goes past attempting to connect to goldleaf via USB. I have installed the drivers numerous times with zadig-2.4.
I have reset the computer. I have tried different computers. I have tried different usb cables and different ports.
As soon as I unplug the usb cable from the pc goldtree then pops up an error saying that an invalid command has been received.
I always start goldleaf first.
Using goldleaf v0.5, goldtree v0.4
any ideas?????
