Here is where to get the catalogues:
http://x.astrogeek.org/software/cdc/catalogs.php
They are self extracting so just run them. You will also need to go into Configuration to tick the required catalogues you want to run.
If it is showing no stars, you are probably on Daylight Mode, you can turn that off in the Toolbar, or, it will change during twilight to the full dark mode.
