I went ahead and posted this in a IRC channel that I know about where there's some folks who can read JP (since I don't..) and a friend said it's saying(paraphrased) "Your flash player is out of date. Go update it!"
So yeah. Go to adobe's site and update Flash, that should solve that issue. (I know, I don't play Chi, I'd hate to have to bug nice folks for translations every 5 minutes; JP in a game bugs me that badly. But I hate errors as much as the rest of ya.)
