If you read as Jorndel posted, stats are saved server-side so if you edit your stats, when the server checks them vs your game and realize they're not equal, it'll throw this error. The only way to fix this is to change your stats back EXACTLY they way there were. If you can even remember them
I did the same thing. But I made it by mistake. I'll release cool hack as soon as I get rid of this error.
I only changed 1 byte of xp number so I have only 255 possibilities to test. I already tested 40.
I also wrote upport ticket to Steam to reset my cloud storage of BO2. I told them that my profile got corrupted and I can't play.
Best luck unlocking your own accounts.
