hmmm... how does this explain the situation from Andreas he described?
Just reinstall now, and it will work
Should I also try to install the first KLAX V2 version and not the newer one?
Just reinstall the current version now, and it will work
And I had never problems with any of your sceneries before and changed nothing at my firewall settings.
It's possible we had a problem with the server config that didn't played well with firewalls, so some of the files might have not be downloaded correctly, it should work now.
