Code can not be used?

[wl00780504]

Hello, sorry, my English is not very good, my dragon age 2 is to buy a solid disc, but the serial number can not be used when registering online, as if the disc has seen the date has expired, but this disc is new Is it possible to redeem the new serial number, or is there any other solution?

If you bought the disc it from a "friend", the code may have already been registered to another player's EA account  If that's the case, "Return for a full refund." 

If not, then which platform? (PC, XBox, or PS3.)
