So I want to start the quest Lost to the Ages.

But, the quest does not activate upon reading " the atherium wars" or when entering arkngthamz.

So I am guessing that a mod somehows blocks the quest from activating. Do you know the culprit or how I can check which one it is?

Any other solution is greatly appreciated.

btw, lost to the ages is a vanilla quest from dawnguard.

UESP has a http://www.uesp.net/wiki/Skyrim_talk:Lost_to_the_Ages#Quest_won.27t_start with a couple of possible fixes.
