Hi Ørnulf,
I didn't see your original message, but a follow-up to Bob's reply:
there are some comments about this at

Basically, the first CD you have doesn't cover asteroids past 9 May
2005. If you put the second disk in the CD-ROM drive, you can go to
Extras... Install to Hard Drive and click on "Extra Asteroid Ephemeris
Range", then "OK". Guide will copy over the files it needs to cover
the next few decades.
