Ubisoft has put up a message on the official Ghost Recon website, regarding a reported Red X error people have been experiencing. "Some users have reported that when initially loading the game, before, during, or after the intro movie, the game freezes and a “Red X” error message is displayed, which instructs the user to restart his/her Xbox. It is important to note that the error does not affect every user, and that the Red X screen itself is a generic error message, much like the dirty disk error messages that other games use." While Ubisoft is looking into the problem, make sure the dik is clean, unplug controllers from the Xbox during the game intro, or just keep restarting until you are successfull.
