First things first, coming to boards and telling off both the Producer and Developer of Black Ops 2 in the way you did is not helping anyone or yourself.
Secondly, if you had searched you would have seen that this problem happens and that there is way to go about it.
You need to contact Cutpurse on our boards. Be polite and explain that you have corrupted data regarding your level. He'll investigate and attempt to help you.
