One fix would be to use MPCORB. I'd really suggest that, unless you
are only interested in low-numbered objects, because the data on the
CD is (obviously) no more recent than 2002. A lot of asteroids have
been found since then.

The other fix that you _could_ use would be to put the second Guide
CD into the CD-ROM drive, and click on Extras... Install to Hard Drive,
and install the 'extended asteroid data'. That'll get you out to 2023.

There's some more discussion of this at

...and of how to install 'mpcorb.dat' at
