I downloaded songs for rockband on my Xbox 360 and it wont play the whole song without saying this. THE SONG DATA YOU WERE ACCESSING HAS BECOME UNAVAILABLE AND THE GAME CANNOT PROCEED WITHOUT IT. What does that mean and how do i fix it?

Make sure you are in the correct user profile. If you are not using the live account that you downloaded it from it wont work.

Possibly it's corrupted. Trying re-downloading it.

go to ur options and recalibrate ur rockband controller.

create a new profile on your xbox and redownload everthing (use download history) this worx for must stuff, but if you have to purchase anything it wont .then ring microsoft they will credit your new profile so you can (this is a real pain and has happened twice to me)

Are you using the same console that you were using when you purchased the Rockband 1 songs? Can you play the songs if you sign into xbox live? If you are on another machine or have ever sent your console in for repairs, and you can play the tracks when signed into xbox live then you need to transfer the DRM(Digital Rights Media) to your new console.You will need your new/repaired machine signed into xbox live and a computer that is online. Then go to www.xbox.com/drm and follow the steps. You will be rocking in no time. Party on Wayne.

You need to play the full game to unlock all 85, but there are a total of 85 songs included.

try the slots in the front, i never use the one on the back of the system to play games,

my rockband guitar works find in gh3

xbox 360 , halo 3 . every thing is set up for xbox live but my ip address keeps failing.
p.s.english please

plug it into the xbox and select an option on it that is `normal` it is probably on intro.

When you get connected to xbox live with your console, you will be able to play those songs, i know it is really unfair.
