MPC get hacked in February and they apparently change all the URL to a new server while all the old URL still give old non updated files.
For 2.76 the file is now: http://www.minorplanetcenter.org/iau/Ephemerides/Comets/Soft06Cmt.txt To make the change edit the file C:\Program Files\Ciel\extres.ini at the section [CBAT_comets] replace url=http://www.cfa.harvard.edu/iau/Ephemerides/Comets/Soft06Cmt.txt by url=http://www.minorplanetcenter.org/iau/Ephemerides/Comets/Soft06Cmt.txt And similarly for the asteroids : at [CBAT_asteroids] replace url=http://www.cfa.harvard.edu/iau/Ephemerides/Bright/$$$$/Soft06Bright.txt by url=http://www.minorplanetcenter.org/iau/Ephemerides/Bright/$$$$/Soft06Bright.txt and replace url2=http://www.cfa.harvard.edu/iau/Ephemerides/Unusual/Soft06Unusual.txt by url=http://www.minorplanetcenter.org/iau/Ephemerides/Unusual/Soft06Unusual.txt Similar change for V3.0 can be done from the menu Setup / Internet / Orbital Elements I change the default values for Monday snapshot so a simple click to the Default button will set the new URL.
