I have been waiting for it to finish installing for and hour and it is still exactly in the same play the blu bar wont move and it is not working!! Help
What console are you using? Try using wired connection or try installing the game again. If you are using xbox, make sure that you still have available space for the game.
Just to add up, if your using wireless connection, try to put the console near the connection and make sure there's no other device connected on the WiFi while you're downloading the content.
