Can't Summon Durnehviir

[LordSarcasm]

I was in the Forgotten Vale with the two dragons on the Frozen Lake, so I took the oppurtunity to summon Durnehviir from the Soul Cairn, I had all the words to his shout, and the first time round went of without a hitch, Durnehviir emerged from the Soul Cairn and taught me the first word of his other shout. Then one of the dragons killed me, so I had to restart the battle, but this time I'm not able to finish Durnehviir's shout. I can pull off the first two words, but not the whole shout. I know the problem about summoning him in an area where's there is enough rooms, but it's a gigantic frozen lake! There is more than enough room for the dragon, and besides the first time it worked perfectly.

I have this issue also.

Not everywhere on the frozen lake is summonable. I had to run around the lake to find a spot that I could successfully use the shout. Perhaps you were lucky the first time?
