yeah its super easy.
Just install and register all your hardware install the traktor pro LE edition, and then NI should send u an email within a week or so with a licence key to upgrade the LE edition to a Full Pro Edition. While you wait for the Serial Key you can goto their website and download the 30 day trial of the Full Tp2 while u wait for the key. Once u get the key just apply it to your Trial version and u are good to go.
I reccomend you download the Service center to get all the important updates as well as sound packs and remix deck packs.
