I also have to say that during the last 3 or 4 years I used a cracked version 3.4 (Hey, I was young and wanted to test it...), a "limited edition" that came with my first controller and now a fully payed Pro version and neither on Windows nor my Macbook I ever had any problems with Virtual DJ.
That's the worst thing about computers. Sometimes stuff that works for everybody else, just don't work for you although it should. :P
