Once VirtualDJ 8 is launched, a Login Window will appear. Login with your virtualdj.com account credentials.

A Pro Infinity, a PLUS, a Subscription License or a VirtualDJ LE Keycode (serial) is required to use the Gemini GMX/GMX DRIVE. Without any of the above Licenses, the controller will operate for 10 minutes each time you restart VirtualDJ 8.

A detection window will appear next asking to use or not the pre-defined audio setup with the built-in sound card of the Gemini GMX. You can still change that from Settings->AUDIO tab.
