I have also tried everything with DNS jumper etc, but still the same problem. Two days ago, when I bought it, it was working fine. Maybe it has something to do with a Win update? I have no idea
Can be useful to use Flush DNS sometimes, to clean DNS cache
I reset everything again, restarted and now get the [Win 5] error
.exe -> right click -> "Run as administrator", now it works =)
OH Nice, so it is a permission problem.
Stupid Windows, thank you my friend
