Help Please - Cannot Install

I just purchased:
Webroot SecureAnywhere® Internet Security Plus 
 
I then followed instructions sent to my email.  
 
I get the following error when I enter my keycode:
 
'The keycode could not be verified at this time.  Ensure that SecureAnywhere is allowed to connect to the internet and try again.'
 
-- I have a working internet connection.
 
-- I 'unblocked' the file in properties.
 
-- I turned off my Firewall
 
No matter what I do, I still get the above message...
 
Any help would be appreciated!
 
Thanks
