My friend is letting me borrow her Traktor Kontrol s4 over the summer. If I'm able to use the deck well enough by the end of summer, she'll let me keep it. The problem is, she didn't transfer the license for the deck to me because she wasn't officially giving it to me. I'm also using the demo version of Traktor Pro 3 because I don't want to buy the software if I can't use the hardware. I'm a total beginner, but I really want to keep this deck and figure out how to use this thing. Can anyone help me out?
