Fallout 3 dlcs won't play

Hi John!

Have you also tried to reinstall your DLCs?

Let's refresh your 360 storage. Go to Profile & system > Settings > System > Storage. On the Manage storage devices > Clear local Xbox 360 storage.

Let's also try to refresh your account by re-adding it.

Note: Before doing these steps, please make sure that you know exactly the email address linked with your gamertag and the password to it so you can add the correct account again.

1. Remove account:
Press the Xbox button to open the guide. Select System > Settings > Account > Remove accounts. Select the account that you want to remove, and then select Remove to confirm. When you're finished, select Close.

2. Power cycle:
Press and hold Xbox's power button for 10 sec. Unplug the power supply for 30 sec. Plug it back in and turn it on again.

3. Add account:
Press the Xbox button to open the guide. Select your gamerpic in the upper-left corner of the screen, move all the way down and select Add new.

Enter the email address for the Microsoft account that you want to add, and then select Enter.

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

Play both, but play Fallout 3 before New Vegas. They're both good, but it would be better to play Fallout 3 first, trust me on this. Also get the full-DLC versions of both.

Are you trying to use the regular fallout 3 disc or the game of the year edition? I've read a lot of posts saying there are problems with the game of the year edition saying it won't work or it won't let you install the dlc. Do you have any other backwards
compatible discs that won't work either or is it just fallout?

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