I've read on the quest page itself here on the wiki under the bugs section that some people have a problem with it not starting. I'm in the same boat as all those guys. I bought all three DLC's when they first came out for PS3, half off sale for a week and then the next DLC would come out etc but didn't start playing it until now. I downloaded the 1.9 patch before starting a new character. I just finished Dawnguard earlier, and I'm starting to wonder if I was suppose to read the book that starts the quest "The Aetherium Wars" while I was in the middle of one of the quests. I can't really find anymore information about it, but I've tried reading the book multiple times from multiple locations where you find it, dropping it and picking it up, putting it on a bookshelf and reading it, pretty much everything I can think of with no luck. Anybody got anymore info on this and maybe a fix to make it start?
