After determining what COM port you are on, close JB software and disconect the USB cable. Plug in the usb cable to your computer BEFORE starting up the JB software. I noticed that when I start the software before plugging in the USB I get the same error

Thank you for the response. After trying a few different combinations of restarting etc, it finally worked out for me. Just had to figure out how to be smarter than the system.

I had to reboot the computer. Then had to tell vmware to connect the USB device I plugged in. You should only have to do this if you have a Mac running windows also. Then I changed the COM port to the one that the jb4 was using and it finally connected.
