You can add your gamekey to our Origin client and download the game via your "My games" library.
Sometimes older games can cause trouble with code redemption directly with the Origin client. To redeem your code with Origin, please try to activate your codes on following activation website instead of using the Origin client for redemption. Get sure that you are logged in with your Origin account. If you having trouble, get in contact with one of our Game Advisor. They can help you to get back in to your game!
Cheers
