A Dawnguard PC Hardware and Software Support section of the forum will be created soon; however, in the meantime, please post here in this thread any reproducible bugs you encounter related to the Dawnguard DLC.

Please first try to confirm that your problem is not caused by a mod, and if so provide the following information below:

1. Description (please use spoiler tags when describing spoilerry stuff)
2. Severity (Minor, Medium, or Severe)
3. Steps to reproduce
4. Your PC specs (CPU, RAM, GPU)
5. Mod load order (please use spoiler tags for long lists like this)

If you think the bug is related to a script error, you might also want to check your Papyrus debug log.

In order to create a debug log, open Skyrim.ini in My Documents/My Games/Skyrim and add the following lines or make sure they are toggled to "1" instead of "0".

[Papyrus]bEnableLogging=1bEnableTrace=1bLoadDebugInformation=1

With these settings on, the game will create a new folder at “...\My Documents\My Games\Skyrim\Logs\Script”.

Your logs will appear inside that folder, in the form of a text file named Papyrus.#.log with the # number ranging from 0 to 3. The 0 log is always the newest with older logs cycling through the increasing numbers. (Note that the text file will be very large and much easier to review using http://notepad-plus-plus.org/download/v6.1.5.html rather than Windows Notepad.)
