Firewall upgrade

I have purchased the AVG Internet Security 2015 with license for 3.  I installed and then had to purchase the individual firewalls.  I was able to load the firewall onto one computer but I am having trouble loading on this one.  Can someone help me?

Hi Amelia,
Did you activated AVG using new license?
Thanks
