You do not even tell us what OS you are using (I assume Windows).
As you cite me (from long ago) I describe the GNU/Linux situation.
If you install the latest client you will have to do a few things:
Fill in your EUMETCast user_name and user_key in the three files
In the channels files all present channels are there but #commented.
So to begin with all data (*) is collected under a default directory.
Receiving the announcement channel but no data can also be an
EKU problem. So check your clients via their WEB interfaces at:
http://localhost:8100 for BASIC
http://localhost:8200 for HVS-1
http://localhost:8201 for HVS-2
BTW the latest client is distributed twice a day in Info-Channeö-1
It comes with a file "Tellicast_V2.14+_windows_installation.pdf"
Hope this helps
