That is strange because I already had that game when I bought the Go Go Bundle Mega 18 where the key come from. I know that the key was old and Go Go Bundle is defunct now but I didn't think the key's got bad after time. I can try see if the game is on sale somewhere and gift you a new key. Sorry for the inconvenience.

I will add you on steam and buy you the game if that's ok. I would appreciate if you marked the key as received when you get the game. Sorry for this :(
