Purchased GTA V from the xbox store this morning all the packs have dowloaded and now get an 'alert' message on the screen saying that the game is corrupt and needs to download further files .... I have done all the troubleshooting and cleared my xbox system cache aswell as deleted restarted etc etc and still getting the same message ??? At the moment there are hints and tips in the bottom left corner and in the right bottom corner the downloading icon and its been like this for 40 minutes ?? Has anyone else had this problem when downloading from the xbox store and how long did it finally take to actually start working??
