I'm assuming you figured this out by now. However, were you making sure you were at the "normal" firelink bonfire? Have you finished all questlines that are still outstanding and beaten every boss. If you have the DLC, did you complete that as well? There was a post on Reddit about this the other day, and they found the problem was that they simply did not return to the normal firelink bonfire, which I believe is the only bonfire that gives you the option to start journey 2. Otherwise, I have no idea, that should not be the case. I bet it's something simple you just missed.
