Hi K2rockall,
Most of the missions that come with the SuperPacks require ships from New Horizons, not just player ships but also AI and static ships.
If you install a SuperPack enhanced ship, such as Bugsier 2, you must already have that basic ship installed. The pack only installs some of the files needed for the ship.
If you don’t have the basic ship, you will be asked for the license key. However, there will not be a way to enter it.
Regards,
Marty
