I am afraid you have missed the boat if you already don't own a version of pro 3 for NX2 as it is no longer available from NIK which is now owned by Goggle. Google sent me an email that said they were moving owner data to their system and would provide support for owned products. NIK was not an arm of Nikon and they do not own CNX2,Nikon does. Right now I am not taking any action to use any other product although I have always owned and use Photoshop CS6 Extended. I prefer CNX2 as it is much easier and quicker to use. I don't know what the future of CNX2 is, but I doubt it is going anywhere, updates continue on a regular basis. Perhaps you can find a version of CEP for sale on line.
