Try talking to the quest giver at the Fighters' Guild about this quest one more time, to make sure it triggered properly. Then talk to Demetrius again to see if you can get the dialogue. If that doesn't work, you'll need to wait until LF2 and the conversation should be available at that point.
For whatever reason, the condition to advance the quest was changed in LF1, and appears to be impossible without an older version of the game. Waiting until LF2 will still work though; just make sure to trigger the conversation as the walkthrough indicates once you can.
