NIS Online - Activation issue on Windows 8

Hello,

 

I just bought NIS.

Installation went smooth, but activation is not working:

Progress bar keeps on scrolling, but after 10 minutes there is no change.

(Firewall is off, and PC has for sure internet connection as I'm typing this)

 

Is this a known issue, and how to fix?

BR,
