@Renan > The MIDI mapping file for Traktor is available from the product page and VirtualDJ 7.x and newer should automatically detect when the R1 is connected and provide mappings for you. If they aren't working or require additional changes, you'll need to make those changes yourself.
@Paulo > You should uninstall and reinstall the drivers, then connect the USB to the computer on a new port.
