Jusy brought a disc with both on, installed it (whilst signed out off xbox live) and both messages appeared. However I decided to save them for later so didn't start either quest.

Then the next day I go on and find out they're both not there anymore!! So I tried to reinstall it.... still no message coming back and the quest definantly isn't avliable to play even though it's definantly the exact same save as before... so I signed into xbox live and tried to do it. It came up saying it;s avaliable for an update but I'm imeeditaley signed out of xbox live whenever I go to update. I found out later there was a dowload section on Fallout 3 main page. Says both operation anchorage + the pitt are installed but it's still not working....;

I've tried to install it several times since and it's still not working. Even when I'm signed out of Xbox live when i go to reinstall it offers me an update which doesn't seem tohappen.... why is it i've not recieved my DLC yet and is it possible to fix?
