Serial number problem
I used my serial number in previous year but after format i had to write that number again and i just received that information: "Your serial number in battlefield bad company 2 has been used before".
Please get sure that you download and install the latest version of Origin at www.origin.com/download (and make sure you have your Origin account ready as well). If that doesn’t helped, close the origin client and go directly to you origin folder C:\Program Files\Origin Games. Run the origin.exe in this folder with a rightclick -> run as administrator. Your BFBC2 game should be still activated with your Origin account and even work on a different computer.
If you still have issues with your game-key, please contact EA-Support. Be prepared to verify your email address, date of birth or any other personally identifiable information on your account.
