Just purchased the DLC and now find out that I can't use it because I only keep a save game on the level I'm in which of course is the end game, Now what Admin... did I just donate my 800 points to Bethesda. Why aren't the instructions posted on Xbox Live before one purchases the DLC. Xbox 360

If you can't do anything else after the endgame, why would you be able to do the DLC. Start a new character.

Every press release about Dead Money clearly stated that this DLC is made to be played before the end of the main game...

I started It using MY first playthrough on 360.Jump on my save before going to the damm .Almost finished in vault now .BUT did not enjoy DLC.
