(SPOILERS)

I have not yet completed the main story line, just got Dawnguard and its awesome so far - except after leaving the Soul Cairn I cannot complete the two misc quests given after talking to Durneviir (Dragon) - learn first word of his shout (even though he gives you all three and I have 6+ souls to spend and have unlocked) or cannot summon him once back in Skyrim. Also after this point I cannot complete ANY misc quests given to me by anyone (they do not go away from menu as completed, neither does marker) and I cannot advance the game any further (to find next 'Dragon' scroll) .... in DLC or main quest! Please help a fellow Nord!!!

You mean you missed the entire section of the forum dedicated to dawngua... Oh never mind

A little tip: putting "spoilers" inside the thread when you have already spit out half of the thing in the title won't save you from being [CEEEEENSORED].

Besides, you've the Dawnguard forum for threads like this.

There is a forum for Dawnguard; use it!

http://www.gamesas.com/forum/195-dawnguard/

If a mod would be kind enough to move this over there. Thank you.

Well, here's the proof of the conversation we had the other day. About those people who despite forum rules would still post spoilers in this forum, even when there's a Dawnguard forum for General Discussion and one for Cheats, Hints and Spoilers.

Thanks OP.

talk to septimus, and go get you a elder scroll.
