not sure where abouts to post this but here whats going on:
Playing Call of Duty: Modern Warfare Multiplayer on Xbox Live:
Around 3.15AM GMT someone (unknown gamertag or would have been reported obviously) did something to my game which did, and has since, corrupted my experiance. I was level 36 and it now says to level up to level 37 i need "50280331". It has also changed from level 36 and level 37 to levels 1 and 2. My current "XP: -50280301"
Everytime i play it takes more xp and does not allow me to level up.
How do i fix this??
I have a photo but im not sure how to upload it
