Re: DLC's
First off, you have posted this in the wrong section, but I will still try to help you.
As far as it only being available in Europe, I don't know why this would be. However, as far as the one time use, this is because otherwise people could give the code away if it was valid more than once. But once you redeem it on your account, it is tied to you account, and can be used on as many PCs as you want. I have reformatted my PC multiple times, and have been able to get EVERYTHING from my Origin Account everytime. You can download the game, etc on as many PCs as you like, but they are only playable when you are signed into an account with those games on the account. For example, say I have Battlefield 4 on my PC and a friend comes over. He can log onto his Origin on my PC and play as himself without having to do anything else, or download anything. He only needs to have Battlefield and the other content tied to his account.
