Which platform are you on, and are you using a physical disc for the base game? 'Transferring game content' is usually copying files from the game disc to the console's hard drive. There could be an issue with the disc (try cleaning it) if it's stopping at the same spot each time. Try clearing your system cache ( https://www.bungie.net/en/Help/Article/12539 ), but if it keeps hanging at 14%, is there anybody you could borrow a disc from to see if the install will get any farther?
