It installs fine,when i go to play the game it says.

 

A-Please redownload the game.

B-The disc is unplayable,please clean it and restart your console.

 

 

I did BOTH.

 

Xbox is working my nerves. Took Fallout3 Two weeks to get here just for this bullshit? 

I had a similar shit with Gears 2. It ended up being a scratched disk that wouldn't completely install. A new disk installed just fine.
