Hi Toni,
After you install Javelin, you will need to install the Jumbo SuperPack again.
Likewise, if you get New Horizons you will need to install the B2 SuperPack again.
A bug in the SuperPack installer allows it to install an “improved†ship even though the original ship is not present. This causes a message asking for the serial key if you try to use that ship.
When you install New Horizons or Javelin it overwrites the SuperPack files. That is why you need to run the SuperPack installer again.
Regards,
Marty
