So my old laptop has given up. I had Traktor Scratch Duo working on it with the AudioDJ4 interface . I thought o.k I'll by an old p.c with windows 8 on it to run the old drivers. Now I findout that neither are supported as Native have changed the Authorisation system and deleted the old one. I spent hundreds of pounds on these items I looked after them and expect to be able to use them. Is there a way around this or is it somewhere on Native Access. It was released in 2010. Thanks in advance.
