I have my code but it says I already used it. I cannot play now?

That's a physical order, unless I am mistaken, so wouldn't your code be with your physical copy of the game? Digital copies of the game obviously receive their registration code digitally, but for physical copies are the codes not packaged in with the game disc?

That's a problem too.
Indeed it is stated that the code is inside the packege but many ppl haven't received their package yet (such as me).
That's why ppl are asking for their codes (as in other threads). SE should've sent to those who bought the physical version their codes through e-mail or the order viewing site too so we're not bound to wait the package arriving.
