Hi, good day.  I just purchased AVG internet security and received the unique code.  When I tried to register/activate it via https://www.avg.com/en-gb/activation, after clicking confirm code, it will directly go to download page.  It is supposedly open another window where I can login to my AVG account or page to input my email address.  But unfortunately, it doesnt show up.  Thus I cannot register the code. 

Any help will be appreciated.
