Diablo 1 HD Hellfire Mod | Awake

On to this quest and every time i speak with her my client crashes, Threw out the book to skip the quest and still crashes when i speak to her. Any fix?

It works to me. Try making a backup of your character and then reinstall the Belzebub Mod

Did you try copying the diabdat.mpq from your CD to the game's folder (again) ?
