You only needed to install the DJM driver if you plan on using it as a controller (for MIDI) or as an audio interface. If you want to link it to rekordbox (to load music in EXPORT mode), no drivers are necessary - simply connect the XDJ-1000's via the ProDJ Link (ethernet) on the DJM-2000NXS and connect the COMPUTER ProDJ Link port to your computer's ethernet jack. In rekordbox you will see a LINK button appear at the bottom left - click that and your XDJs and DJM will appear at the bottom of the rekordbox screen.
