I can't seem to login to Twitch through the app in order to authorize my account. It was never connected to Justin.tv and I don't get an error code when I try to login. All it does is refresh the page back to blank. I've tried using the Enter key, clicking on Login myself, and nuking my raptr.cfg file, but nothing has seemed to work.
I went ahead and created a ticket for your issue so we can try to get to the bottom of this. Ticket # 6245
