Fallout 3 dlc not working

Yes. I have fallout 3 and fallout new vegas that played perfectly. The fallout 3 stopped launching after I downloaded some DLC and stopped working tho

I have the GOTY of fallout 3 and it works perfect! my only problem was figuring the dlc for the game I would install the dlc but it would not show when i load the game...... I find out when you install fallout 3 then the dlc you have to keep the dlc disc
in the tray in order for the dlc to work unless you bought dlc from the store this is how you play the game...

Remove the DLC's and just insert Fallout 3. Manage Fallout 3 and install the DLC from that screen.

The Known Experience Concerns states that the retail non-GOTY DLC discs should work if I have the digital version of Fallout 3, which I do.

"Fallout 3: You will only be able to play disc based DLC for Fallout 3 if you also own the digital version of the game. Disc based DLC includes the Broken Steel and Point Lookout disc and the Operation Anchorage and The Pitt disc. This restriction
does not apply to the Game of the Year Edition."

So in my case, it should work but does not. The DLCs are downloaded but not recognized when they should be.

I have a fallout 3 problem myself. I have fallout 3 GOTY, my game disc does not read well on the one but the 360 it reads fine. the dlc disc of fallout 3 is fine and can read on the one.

Because I preordered fallout 4 I got fallout 3 game itself for download but no dlc with it so I put in the dlc disc and the console installed the dlc no problem. I run the game and check downloads and none of the dlc shows up at all not even when I load
the game but it's on my game manager as installed...
