I'm not sure if this is the right place to post this problem, but here's hoping someone will help me out. So here I was playing Call of Duty 4 MW in an online match, when suddenly I was kicked out and returned to the main page. When I get back to the Xbox Live screen, my rank was reset, my scores and experience was all messed up (too many numbers) and when I went to Find Match, all the options were greyed out, hence my reason for posting this.
I do believe this may be a prank by some other players, considering the game I was in was majorly infected and just screwed up. If anyone could help me solve this or just give me some advice other than "Erased all data and start over" I would very much appreciate it. Thanks!
