Ok, so I have my virtual dj pro running on my toshiba with my Hercules RMX controller. I got a new Dell Laptop. Installed my VDJ on that pc, everythings good, then I installed my RMX Controller, that installed ifne. BUT when I run Virtual Dj, and choose the external controller interface, I get nothing, no blue lights nothing. NOt sure if I need to adjust or fix something. Can someone help please?
