I am in the Ratway and I am doing the quest to find the Esben. I am at his door, but when i speak to him through the door, he has no voice and after he says that he will open the door, he does nothing.

Two ways to fix this (both do not need to be done):

1. Unpack the Skyrim - Voice Extra.bsa files into the data folder, or download it already unpacked http://files.gamebanana.com/sounds/skyrim_esbern_voice_fix.rar. Unzip the contents and place them in the data folder.
2. Navigate to C:\Users\Name\Documents\My Games\Skyrim and open the file Skyrim.ini with notepad. At the very end of the file, add the following text and save the file.

• sResourceArchiveList=Skyrim - Misc.bsa, Skyrim - Shaders.bsa, Skyrim - Textures.bsa, Skyrim - Interface.bsa, Skyrim - Animations.bsa, Skyrim - Meshes.bsa, Skyrim - Sounds.bsa
• sResourceArchiveList2=Skyrim - Voices.bsa, Skyrim - Voicesixtra.bsa
