On the Xbox, leave the game at the title screen while you download the soundtrack. If you move into the menus and start poking around, the download will likely stop. (It definitely stops if you go into the music store.)
It might be faster to start the download from in-game, and then quit the game and allow the download to finish while on the dashboard. I did that for the second half of the download, and it went much faster than the first half.
Its fixed today, could be because I am in Europe. Everything seems to be working ok now.
I, too, am having troubles unlocking/downloading RB Blitz songs. I downloaded the game Tuesday night along with the unlock key, start the game and skipped downloading the songs (I didn't know what it meant at first and I just wanted to try the game). Now the game no longer gives me the option to download the remaining songs. Am I SOL or is there a way to download the songs? I tried uninstalling the game and re-downloading it but no luck. Any advice would be great. I called Harmonix but they told me to e-mail [email protected].
I have a problem with the song "moves like jagger" in rock band 3. I have got all the other songs from the soundtrack. When I go to pick songs, it says viewing 383 of 384 songs, so I have the song but I cant see it and cant play it. WHY? Can someone please help me?
