Hi David,

Simplest way to fix this :

(1) Make sure you're using the version of the Guide 9 software from

http://www.projectpluto.com/new.htm

You will see, among other improvements, "(2012 December 12) Fixes
and improved display of comets". Which is partly why I recommend getting
this version.

(2) The "improvement" involved having Guide use comet orbital data
from the IMCCE in France, plus the Minor Planet Center's comet data.
The only sticky bit is that the IMCCE has gone silent, causing Guide's
automatic comet retrieval to break. (As you found.)

So instead, try downloading this file:

http://www.projectpluto.com/eltdat_g.txt

(about 193 KBytes) to your Guide folder. This is the last version
of the IMCCE data, from August 2015.

Then, download the MPC file directly :

http://www.minorplanetcenter.net/iau/Ephemerides/Comets/Soft02Cmt.txt

And save it to your Guide folder... _changing the name to
soft02cm.txt_, i.e., drop a 't' from the name. Upper vs. lowercase
doesn't matter, at least not in Windows.
