I purchased both Honest Hearts and Old World Blues today, on Steam. And, after getting them installed, I launched the game. Now, the game loaded fine, but once in game, immedately my screen fades to black and my character makes drowning noises. Moments later, my HUD re-appears and it sounds like I'm being attacked by ghouls. I did a quick spin the first time, saw nothing, and then it happened again. I won't STOP happening. Even on a new game, it won't stop happening. It is unplayable. Bringing up my pipboy delays the onset until I drop it. It even occurs during cutscenes!

Help?

For some players, the update is messing with Beatrix Russell's script. http://www.newvegasnexus.com/downloads/file.php?id=42729 *should* fix your game.

Yes, it did! Awesome. Thank you, very much.
