Trouble with new computer

I recently stopped using my laptop with the CNC machine and purchase a desktop computer, I installed the driver and all files needed but now when I turn it on, I have to unplug the USB and plug it back in for the software to see it. Once I do that, I start the carve and it goes through the set up process where I probe and set everything up, but then will not move once I hit carve. Can anyone help me with this?
