I have spent the last two hours trying to register Sins so that I can update the game with the latest patch. I've entered the number with and without dashes and in lower and upper cases. I've also tried to do it from within my stardoc central account and from within the game itself. I'm get a message saying that either it is an invalid code or something does match my e-mail address. I frustrated beyond belief. All I want to do is register and enjoy what looks like a good game. Has anyone had the same experience.
