Install error

Recently, I downloaded the mission pack for Star Wars: The Force Unleashed. Now, when I tried to install, it gets to about 14%, and then hits me with the error code "80029564." I've tried it several times, and it always happens. Now, if this was a demo, I wouldn't be mad, but because I payed money for this, I'm starting to get a little frustrated. I've looked online, and found no real help. Does anyone here know the solution?

If it makes a difference, I downloaded it in the background while playing another game, and I'm using a wireless connection.

Sounds like it's corrupt, try downloading it again.

Seems like a ton of people are having this error link

just redownload and try again

If it happens again try not using download in the backround and see if that helps.
