CdC will work, but the process of loading new orbital elements
by replacing the Visual.tle file in the cat\satellites directory is
not properly documented. The quicksat.mag file should also be
updated.

The ability to predict satellites is under the "calendar" menu.

Contact me (mmccants at io dot com) if you need more help.
