Hmm. The manuscript is in the still ruins, and I've read that even if you pick up the manuscript first and then given the quest, you should be able to complete it.
To translate the manuscript you have to go to the war table, and there is a mission you have to unlock/complete. I think its called Translate the dragon script or something like that. And once its done, go back to Frederick.
That is the problem I am having.
It won't let me find the manuscript, give it to him, or do the mission at the war table.
I have to go to Skyhold to judge the next group of prisoners so I will double check and edit this comment on whether anytihng changes or not.
EDIT: Same as before.
Can't find manuscript/may have already found it, can't give it to Frederic, and no new mission at the war table.
