I had the exact same thing as you yesterday man...
Then I fixed it. Its really easy all you have to do is
1.) when you see that message press NO.
2.) Download the 4.65 spoofer on your ps3.
3.) Then after you download it on your pc it should come up as a pkg.
4.) install the 4.65 spoofer (pkg) into your ps3
4.) your ps3 will restart...
6.) After it restarts go to Rebug toolbox enable Rebug mode
7.) After you enable Rebug mode go to multiman
8.) when your in multiman go to Cod advanced warfare press triangle then copy...
9.) After you press copy it will ask you a question select YES.
10.) It will take a long time to copy so wait (it may be faster depends on your internet connection speed)
11.) after it copied you should have 2 advanced warefare game on Multiman
12.) hover over to the second on and press triangle the press load
13.) It should the bring you back to the Playstation Sign in menu
14.) click on Advanced Warfare
