Weird problem

So I've owned Bo2 WiiU for 2 years now. I've been able to play all modes just fine then. I decided to play Zombies again. Everytime I select Zombies, after 10 seconds I get an error code 150-1031. This does not happen with multiplayer or campaign. I don't get any error codes with any other games either. It's just Zombies on Bo2! Help appreciated.
