I am expanding my own message.

Now after I have updated the mpcorb.dat file manually, Guide9 crashes
also if I try to update the files for comet data or critical list
objects with the Add MPC comets/asteroids menue.

The problem is surely not the internet connection. Because I can open
all this files on the MPC site
http://www.minorplanetcenter.net/iau/Ephemerides/Soft02.html very fast
in a browser.

I can see on the upcounting kb numbers that Guide9 is downloading the
file for several seconds and after that the immediately following lokal
update process seems to be the cause for the Guide9 crash.
