Let's start with the basics.
Attached is a little debug program. Download and rename without _file extension (ie. so will be.exe).
Run and should show you a little message about what program it is attempting to connect with.
If you activate Ecco you should see this message, and be able to press shift+control+c to copy the message to the clipboard.
paste back the message shown from Ecco, (and if that does not work, let me know and manually type in the message shown).
to exit just double click the tray icon for the program.
if all works as expected, please do for ecco with and without the extension running (if possible for you).
