1- hover over the hard drive click "Y" clear cache. Ok. 2- Hover over hard drive click "A"/Select "System Settings" ?Select "Content Cache"-Delete Didn't have this option. The closest was "cloud cache..." (or something like that). In any event I deleted it. 3- Reboot the consule Ok. 4- Go back to the hard drive. Open the Game, and look at all the files to see if there is a yellow exclamation next to any of the files. No files with yellow exclamation. 5- Go to "My Games" section on the home screen. Open Destiny the TTK, and download missing or corrupt files. (I just let it download them all, took less than 10 minutes for mine) ok. It took about 10 minutes as well. 6-Start the game and when it is connecting it will finish update. Back to the loop! : ( Asked to download everything once again. I'm from Brazil. Maybe there's some problem with the Portuguese version of the xbox 360. oh well... Lets see if Bungie figures something out. Thanks for trying to help me, my friend! I really appreciate it!!

Where are you trying to launch/start the game? I thought that If I clicked on TTK icon in "My Games" that the game would start, but I too kept getting an install loop when I did. I actually clicked on the older version that said "Destiny" to get the game to play. I am assuming that the TTK version is just an update/expansion. And that the original version holds all of the coding to launch the game. May give it a try, it can't hurt. Wish I could be more help, but I am not a professional. I just know what a struggle it is, having been there myself. Good Luck!
