Did you get a code with it? If you used the code on the website, you should be fine (assuming you have not used the code on a second account). If you redeemed it through Origin, it would cause problems and you would need to call in. Here are their numbers, they are pretty good at this kind of thing and should be able to get you sorted quickly. Skype is probably your best bet to call in on.
