I downloaded the TNG software and followed the instructions to install. After I upgraded the controller firmware and drivers, I cannot use the old software. I do not have my license key yet (hopefully in tomorrow’s email) so I tried to do some work with the old software. Now nothing is working. ;-(

Is the new firmware backwards compatible with the old software?

If you want to use CNC USB controller software once your controller is updated with PlanetCNC TNG software:
-In PlanetCNC TNG click: Machine/Controller/Advanced/Revert to V1
-Close TNG
-Open CNC USB controller software and update firmware: Machine/Update Firmware
