Worked for me as of 6:13pm CST. I have redeemed the specialization unlock, so perhaps there is some truth to that theory.

@Zelyre: Hmmm... Yeah, I can see where you're coming from, it definitely does have more than a few instances of that kind of thing happening; but overall I would say that Trigun doesn't completely rely on the "wacky anime" shtick, and has plenty of other more memorable moments that don't involve what is now a cliche in anime. In all honesty, I would probably compare it to the way that FMA: Brotherhood handles itself. It has those wacky anime parts, but also has plenty of other more serious moments that are what I personally enjoy much more, and feel like are what makes the anime worth watching.
