Long story but i hope you can make sence of it....
I play modern war on my girlfriends ipad, I am a medium gold user and she often hits the roof when she gets an e-mail saying shes paid for "gold" (She doesnt understand why i need it lol). So What i want to know is what i have to do and how i can do it so i can use my bank details. I have created a apple ID with all my details on it and i have signed out of her account on the ipad and logged in with mine, however when i go to by gold i get a pop up message saying that i wasnt one who installed the game - meaning my girlfriends ID did and that i have to download it again using mine.
My main concern is that i dont want to loose my game by deleting it from the ipad and downloading it again only to have to start from scratch.
Any help with this matter and i will be greatfull.
Many thanks.
