COD GHOST not working

[canonuevo]

After I did the update (for cod) since I haven't been on for a few weeks, it just goes to a black screen on start up. I tried uninstalling and reinstalling and still no luck. Any ideas? Any help would be gladly appreciated. Thank you.

Powering down the console completely (unplugging the power cord) did the trick for me in the very same situation.
