hello Emilio

you need to install the dongle drivers onto any new machine. Make sure the dongle is in one of the machine's USB ports, open the Catalyst application. Then go to the Help menu and choose the Install Dongle Driver option.

After the drivers are installed, restart the application. The red LED in the dongle will come on indicating the computer can see it and you should be good to run the software on that machine.

I hope that helps

regards

Nev.
