I mean, it was exactly less than eight hours between your two posts, so I don't know how fast you were expecting a response. In any event, did you use the old e-mail or new e-mail when requesting the serial. If you used the new one, I'm guessing that's why. You would need to e-mail FSDreamteam with both the old e-mail that you used and the new e-mail that you wish to use, so they can make the change for you.
