I checked with my husband and he seems to think it can still be used, although he did agree that some games that is not the case. I'm a little distressed right now because I am unable to delete this auction at this point and I really don't want to misrepresent what Im auctioning (knowlingly or not).
In reference to the above statements regarding whether or not the key code can be used again, I would like to add for the winner that if the game does not work for you I will gladly refund your credits to you.
