I was playing Assassin's Creed 4 Freedom Cry dlc today and I ended up getting the Firepower achievement for killing 5 guards with one blunderbuss shot, the cheevo popped and my console froze, I rebooted the system and continued to play with no further interruptions or freezes, however when I completed the dlc and I had achieved 100% synchronization and the credits began to roll I wondered why no achievements were coming up, for completing all mission, doing a certain objective on the final mission, and finally for achieving 100% synchronization in all mission. I completed all of this in my one playthrough that took me about 7 hours. Now, as soon as I got back to the game my console froze again. I rebooted it and this time I'd sign into live like normal, but whenever I ran a game it would kick me offline and wouldn't allow me back on live, but returning to the dashboard would sign me back in, I took this as my profile being corrupted and deleted my profile and recovered it, now I can't even run a game without my console freezing. I tried to start the game and THEN sign in and as soon as my profile signs in the console freezes again, I've deleted and recovered profile several times, I've cleared my cache, and I've uninstalled and re-installed the disc. I don't know what else to do and I would really like my profile and achievements to show up. Help please.
