I lately started to use BD and It seems to be a good software. Altough I have a very annoing problem.
BD service causes An Illegal operation in my office. In home and behind my customers cable It works great.
I tested it in my home over wifi or over cable and no problems.
In my office I'm using a cable and BD service gives me Illegal right after start.

In my office I have a static IP, but it should not matter. Only difference is network mask with .240 ending.
Before BD Internet Security I took a look to BD Total Security. I uninstalled it before installed BD internet security.
Maybe something did not unistall correctly?
