First of all, you have to know that every game has an own, new andpersonal activation code. The activation code can only be used for the game you ordered.Therefore you should keep every activation code you get. If theactivation code won't be accepted for any reason, please download thegame and then install it again. If this doesn't help, please contact the support team via the SupportCenter. When doing so, make sure you insert the transaction ID or thebill ID of your purchase so that the support team can be sure that youreally purchased the stated game.
