Hi, I purchased AVG VPN (single device) for Windows on my PC last November but never activated it. I have downloaded the AVG VPN app for my Samsung Android phone. However, although I entered the unused activation code from my subscription details it won't open. I am in Spain for 3 weeks and tried to start a new subscription but won't allow me to pay for that here! Anyway I can transfer the subscription? Cheers Mark
