Full Fix Solution
In order to register/enter the activation key in nQuery/nQuery+nTerim, you need to be logged onto the machine under the same profile as was used to install nQuery. (This is because the registration process writes some information into the registry keys HKEY_CURRENT_USER).
If you log onto the machine under whatever profile was used to install, then enter the registration/activation key, it should work OK.
