I am on the Touching the Sky quest. I have filled the Initiates Ewer 5 times and trying to gain entry to the Inner Sanctum. I pour the water in the basin and the door unlocks. When I activate the door to go in, my system crashes. I have to reboot my Xbox and reload the game. I have tried to gain entry 5 times with no success. I have the game installed on my HD. Any suggestions?
