Re: INSTALLATION: PRODUCT KEY ALREADY USED

Did you enter the key twice? Does the game show up in Origin under the account you used to enter the code the first time? Did you try to log out of Origin and log back in? It is possible your code was spoofed. Where did you get the code? As this is a public forum this issue can not be discussed here. You need to contact EA customer service.
