The solution is likely replacement of the button switch portion. Be careful of applying too much pressure... often they have plastic hinges for the buttons and they can be broken by applying too much pressure in an attempt to get them to work.

well what software are you using. They is plug n play capable w VDJ and the drivers if there any should be on vestax's site or on a disk that came w the software. and if you need mappings for it meaning to your controller works with tratoktor www.djtechtools.com like i said you might not need a driver for it but let me know

It is an either/or thing. I would recommend you get a headphone amplifier or get external speakers and drive them externally. Internal speakers are relatively poor quality anyway

Go to the customer support for the product.

Take it in for repair... this is NOT a DIY project.

The problem with the DN-SC2000 is the firmware. It is being re-written and should be released soon.

and download the .tks file for your version of Traktor. Suggest you save it to the Traktor program directory.

Then within Traktor in the controller settings section, load the .tks file, save and you're good to go. Obviously you can tweak the configuration as much as you like once it's loaded. Suggest you always keep a backup of the original.
