I recently purchased New Vegas and I love it (although I've had some bug related issues such as save games not loading). A couple days ago there was a deal on the marketplace where Honest Hearts and Dead Money were half off. So I bought them, but now whenever I start up New Vegas, I just get the black screen (crash since I can't even open up the dashboard). Removing the DLC doesn't help either.

It's a new disc, there's no scratches on it, and I'm not having problems with any of my other games. Clearing the cache didn't help either.

Please help.
