I bought Dead Money the day that it was released. I didn't try to play it until the PSN outage. Dead Money isn't listed in the DLC on the Main Menu. It looks like I'm having the same problem that everyone was is/was having. I cant get the radio signal to start the DLC.

I deleted the DLC and reinstalled it, not working.
I waited 10 minutes (Real Time, not game time) for the Radio Signal to pop up.
I know its downloaded and installed because I'm level 31.
My save is pretty far from the last mission (Hoover Dam)
I created TWO new characters and still not working.

What should I do? I know that I'm not buying HH till this [censored] is fixed!

After messing around I found a solution:

1. Delete your Fallout: New Vegas game data (not your save data)
2. Disable your PS3's internet connection (so it won't patch)
3. Let the base game install (pre 1.05 patch)
4. Enter the Brotherhood Bunker and save
5. Re enable your PS3's internet and patch
6. Load your save

EDIT: Nervermind... Once I reloaded my game, I spawned in the Mojave Desert with a invisible gun and all of my weapons are gone.. I went to the bunker and I cant get inside. So it looks like I have to play the DLC with the game unpatched. This is sad...
