I have dm and hh installed on my 360. I allready played through hh (didn't like it) and went to start dm but it still says I need the key to get into the bos bunker! I think I've got the most recent update (1.3.0.444) so why doesn't it work? I thought the update that came out before hh was supposed to fix it. Sooooooo.... now what?

Im having the same prob and its annoying that i paid $10 for something that doesnt work...

Seriously... u buy one game and it cancels out the other...wtf? Dm worked before I bought hh. So im really confused and slightly disappointed.

I have the same problem, even though I haven't got Honest Hearts. I was so mad when I had done another playthrough of the game just so I could play the DLC...
