Are you trying to DL Dead Money from the marketplace or the main screen of the game? I think you should delete the Dead Money DLC if it is partially installed and re download it from the marketplace (not the main menu of NV), then clear the HD cache and start the game. It should prompt you to download the patch and it should work fine...at least it did for me on the first try.
There shouldn't be any issues since you're on a console there obviously can't be any compatibility issues.
The only thing I know for a fact is that if you've got Dead Money installed on the HD and you decline to install the patch when it pops up the game will freeze every time.
Good luck, let us know what happens.
Yeah, I cleaned the hard drive cache, the game cache, redownloaded both the DLC and the patch - still crashed the game. I'm not taking another chance on losing a level 30 character - I'd like to play this one to the end, start another game and then fiddle with the DLC and patch on the new game so I don't lose a whole played game again.
