Would that be the product key? That's the only place I can see to enter anything at all. My online installer for ad2 says everything is fine so I didn't want to take a chance and type a serial number where it says product key.
Yes, the product key is what you enter at the XLN website. Then, you'll be given an option to choose your 3 adpaks, midi, & kits.
Open the AD installer and update.
