Unable to turn on VPN

Hello Rommel.
We'd be glad to help.
Please make sure the paid subscription of AVG Secure VPN is activated (https://support.avg.com/SupportArticleView?urlname=Activate-AVG-Secure-VPN) using the activation code. If it is, please restart your PC once and try to turn on VPN connection. 
You could also try to click 'Change location' and connect to a different VPN server.
