Back compatible game freezing at launch

There are no error codes or anything at all. It just sits there. Eternally. I do however own it digitally. I have not had any other issues with any other games though, no.

After you clear the local storage always remember to hard restart

Hi DrknessRisen419,

Thanks for the reply! When you clear the 360 storage, you shouldn't lose your progress if you've been connected to the internet. Your progress is saved to your profile in the Cloud while you are not in offline mode.

In addition to clearing out that 360 storage as recommended by the other XBF and the local storage by our Ambassador, you may want to also try removing and re-downloading your profile in the 360 emulator as well. Just launch any 360 game, and when
you see the 360 animation, give the View & Menu buttons (small ones in center of controller) a good press. This should bring up the 360 Guide and you can perform the action there. Here are the steps if you aren't familiar with them:

Hope this helps out!

Hey DrknessRisen419,

Thanks for reaching out to us today. I'm sorry to hear about any issues occurring with Assassins creed 4 Black Flag. Do you get any error codes or messages when the game freezes and closes out? Is this game digital or do you own it via disc? Do you have
issues with any other games? By any chance have you gone over our article
"My Xbox one game won't start or freezes during gameplay"? It has a bunch of troubleshooting steps to go over, give it a shot.

Hope to hear back soon.
