Need more information. Links to specific URLs that you are going to would be helpful. It sounds like you're trying to register the BF4 coupon-code that you got inside the box of your XFX R9 290 at XFX's site. I do not think that's where you need to go.
EDIT - found out today that some of AIB's (XFX, Sapphire, etc..) are asking customers to register their product with them before getting the code. If this is what you're trying to do and it's not working, definitely contact the AIB for assistance.
We're trying to keep the promotion site (linked below) updated with information about how each AIB is executing this promotion. Sapphire and XFX currently have "Learn More" links for there name.
