Connecting XDJ1000 MK2 to DDJ1000 SRT

Having trouble linking my XDJ1000 mk2 to my DDJ1000 SRT. When hitting link on the XDJ, I am able to click USB connection but am unable to scroll and select a deck I want to assign it to. My laptop is fully up to date, as are my XDJs, DDJ1000 SRT, and Serato. What could the issue be?
