I've recently just bought DDJ Ergo K and I've upgraded it from Traktor LE 2 to Traktor Pro 2. But after I activate my Traktor Pro 2 and I start it, I can't seems to be using the Hot Cues buttons on the DDJ Ergo K, same goes to the Sampler Buttons. There are still other dials and buttons that is not working well. I've tried researching online and totally get no answers, I've also tried to update the firmware of the DDJ Ergo K which is 1.20 and also I am holding the latest version of Traktor Pro 2 which is the v2.5.1. According the the Setup Wizard, I've also out DDJ Ergo LE and everything in the settings was set correctly as I followed the manual, can you all please tell me what is wrong? If not I really feels that I spent a bomb on the Ergo and totally have wasted it. I've tried with Serato DJ Intro and everything works fine.
