I have the same problem.
I also managed to skip 80% of the hunters edge quests by answering the jarl that im a source hunter
-->He attacked me and i had to clear the wqhole village from barbs and orks.
As i managed to get into the wizard quest by destroying the boulder and finding the family, this didnt get me stuck in the story but the blood is really required.
I am sure of colleting it in the library but cant remember having it seen in my inventory.
It would be lovely to fix this somehow...
I have uploaded the report here: http://www.file-upload.net/download-9195075/report.zip.html
Note that i only included the latest savegame to keep it small...
