I gave a look into other issues posted but I couldn't find any look-a-like to my issue. Maybe I'm even doing something dumb but I couldn't workout what am I doing.
Launching the program for the first time it seems to be running, but no vpn or internet is brought up.
I looked into the tutorial in the homepage again and did everything from zero. No result. I'm posting the cut-log of the window so you can workout something.
