After our developers have done extensive tests on this issue, we have reason to believe that this is most likely the result of a conflict with your PES 2014 online login and your PlayStation®Network account login.
To avoid this inconvenience, we suggest you to go in game and from the Main Menu select "Online Settings", then select "Auto-login" (last option in the list) and set it on OFF.
This should prevent the online access conflict resulting in your console restarting. If the problem persists, you may also want to untick the auto-login option on your PlayStation®Network account.
In a future update, there will be certain amendments in order to avoid this conflict as well as making the use of the auto-login more convenient for our players.
