Hello Carol,
If you have purchased AVG Secure VPN for windows PC then it cannot be used on Android or iOS devices.
You have to purchase Secure VPN from Google Playstore for installing in Android and "App Store" to install on iOS devices.
You can just log out and enter the correct AVG my account credentials on AVG Secure VPN interface.
Open AVG Secure VPN window on your windows PC.
Click on "Connected" at the top and select "Log out".
Click on "Log in" and enter the correct "carolisaac56" AVG my account credentials.
