When I go in to enter an invite code, it says "you've already used a friend code". When I first created an account, I know I did use an invite code. However, I forgot my password (and the password for my email) and so I created another account. When I tried to use an invite code, it gave me that message. Then, I used a different invite code but it still gave me that message. Does anyone know how to fix this? Is this a bug? Do you guys have the same problem?
