@davey – Thanks for clarifying your steps. Hopefully others can benefit from this information.

So if you don’t have a save before picking up the blood scroll, you are stuck until they fix the problem.

Also I have uninstalled hearthfire and completed the dawngaurd questline and reinstalled hearthfire and had no problems at all.

@Trent – If you uninstall Hearthfire, then everything associated with it will be removed from your game. I can’t answer whether the saves themselves would be removed, but I would imagine not. However, without the Hearthfire add-on info the saves could become corrupt or otherwise not load properly which is why I’m stressing caution if you decide to do it. If you have a save prior to Hearthfire, then I’d say you’ll be fine. If the only saves you have are after Hearthfire was installed, then you’re running the risk of damage to your saved game (imo).

Bottom line: If you can wait to see if Bethesda issues a fix, then I would. Wish I had a better answer for you.

@Lee – Thanks for checking back in. I can understand why you don’t want to lose all that time spent on Hearthfire. I’ll keep a look out for any patches and continue to post other methods for fixing the problem here, so check back every now and then in case something that helps you pops up.

@Trent & @Lee – It looks like Davey (see previous comments) was able to read the Blood Scroll after uninstalling Hearthfire. However, he had a save point that he could revert back to, dated before the reading of the Blood Scroll. Additionally, all Hearthfire progress is lost in this method. If you don’t have a save point from before the reading of the scroll, then you may be stuck until a patch is created or another workaround is discovered.

It sounds like neither of you have a save point from before reading the scroll.
*** NOTE: I am not endorsing the uninstall of Hearthfire as a fix for the Dawnguard Blood Scroll issue. You do so at your own risk. ***
@Trent – If you decide to uninstall Hearthfire, please report back if it fixes the scroll reading problem.

@Lee – Since you have to replay Dawnguard (if I’m understanding properly), it’s likely the uninstall method is your only option as well. Please report back if you uninstall and it fixes your problem.

@Davey – Glad you were able to finally read the scroll. It’s too bad you had to lose so many hours of gameplay. Thanks for adding your experience here though, I’m keeping a running tab of folks with issues. If I get a significant amount I’ll send the info off to Bethesda.
