My understanding of the NVH licencing is that the the interface / scope are linked together so obviously Pico does not know the details of what hardware you may already have or what scope is purchased with NVH interface.
If you purchased through a distributor surely they will deal with the licencing? If not then all that is required to fire-up the whole shooting match is either a phone call or an email to the guys in support at Pico. They are great people and will have you up and running in next to no time.Contact Details
