I have downloaded all the DLCs and the classic pack for the game and under downloadable content at the main menu, it shows that no DLCs have been installed. Is anyone else experiencing this issue?

I purchased the Collectors editon end of April and was able to use the Classic Pack in normal mode. I started a new game on hardcoe mode after the last patch in May. Now I have no DLC. I am going to try to delete the initial install of DCL and retry a new installation from PS Store.

Did you install the DLC's after downloading them?
Have you deleted your gamedata recently?
(deleting the maingame data usually means you have to redownload the DLC).

no i never deleted anything. I only recently downloaded and installed the DLCs after the PSN store came back up.

One of my online friends on PSN said he can't get his DLCs to work either. Is anyone else having this issue? I just bought a PSN network card so I can pick up these two DLCs. I guess I won't be in a hurry if its not working for people.

I'm having the same exact issue. I've downloaded both of the DLCs but nothing shows up. Looks like I've just wasted 20 bucks...

I had the exact same problem recently. Do you have a save under your Game Data Utility that says Fallout: New Vegas DLC (CA) ? If you do, try deleting it. Apparently it's causing issues due to being the wrong region or something. After you delete the data check your game and see if your DLC reappears. You should have it all back. However, if you're missing the Classic Pack try re-downloading the French version by checking your download history. If the (CA) data reappears under your Game Data Utility again, delete it and everything should be fine.

It worked. You are awesome. Thanks!
