As some of the other plays have downloaded old world blues, just like me.
I downloaded it while playing Fallout New Vegas, When it got downloaded or finished downloading, I was yippe-yippidy yay, Now the quest wont pop up, And I cant find the quest to start Old World Blues,I am at the Mojave Drive-In,Sattelite wont pop-up. Please help I am getting Impatient at the moment. Thank's!

Try not playing it while re-downloading it. That should do the trick.

If not wait around, it might pop up then.

restart the game
