Check the file "add_mpc.hee" in guide folder and open it with notepad as it is a text file.
The main internet line should be this one:
^Click to download updated comet data and add it to Guide//dhttp://www.minorplanetcenter.org/iau/Ephemerides/Comets/Soft02Cmt.txt soft02cm.txt;dhttp://www.imcce.fr/fr/ephemerides/donnees/comets/ASCII/ELTDAT.TXT eltdat.txt;a2789^
If it is not, use this one. Save it in the Guide folder.
