Hi, this morning I was playing Zombies mode on world at war after having downloaded the map packs. I was playing the zombie level from the third map pack. It was a 4 man team and as soon as the game started I guess someone "hacked" it because he was able to float? I then got a message saying "You have been killed" "You have been frozen" and I got kicked from the game. I then saw that my level had gone from 25 to level 1. No big deal, but then it wont let me play online anymore. I do not get a message saying I am banned or anything, It just says I cant play any core games because I'm not even level 1? I went to barracks and checked my xp which had somehow become -(insert large number). Can someone help rectify the situation? I did nothing wrong, and would just like to play online again. Thanks, Jaws of Fire.
