It's called "Virtual dj 8 pro"
There's a lot of cracks out there already BUT the creators made it impossible for the program to recognize the external DJ controller.
I'm sure it would save me and a lot of other people both money and time! And the same time you'd probably get donations as well because us people have been without a crack for over 3 years!
I guess it's pretty easy to bypass it but i'm not a coder so i can't do it!
