My Photo Vault in AVG Antivirus Pro (Samsung Galaxy S7) suddenly doesn't recognize my 4-digit PIN. In fact the screen says "CREATE Security pin" at the top, and "Set a 4-digit PIN" mid-screen. I never get beyond "Re-enter your PIN" on the following screen (there's no "OK" or any other button other than the back arrow "Create security pin" at the top left).

So I not only can't access the photos that are in there, but I apparently can't start over and use the Vault at all?
