So i have read just about every thread regarding the DLC issues and it dosnt seem to be working.

I installed fallout 3 with the disk and installed the DLC with the disk 2 like one of the threads stated.

After installing the DLC it finished, no errors what so ever. I start a new game play for an hour and i have not yet had a radio transmission relevant with any of the Expansions. so i can only assume my disk 2 and expansions are not working.

what may be the problem here and how can it be fixed?

Did you use the "Data Files" option in the FalloutLauncher.exe menu to turn the DLCs on?

And have you patched the game to the latest version?

I had to manually start the launcher to figure it out. I must of just over looked that. Thank you
