Activation problem

Hi 

I have problem with Norton 360 activation. I have three licences nad I had Norton 360 installed once on my PC but removed it to use on other computer. Now I'm trying to activate it again (not exceeding licences number) but after clicking "activate now" only box informing about process appears and nothing more happens. I attach screen. Sorry for Polish on screen :) I tried to remove malware as it was suggested in one post but it didn't help.
