Hey guys, this is my first time using this site so I apologize if I'm posting in the wrong space. I came here because last night when I was playing my (still) favorite game Call of Duty: Modern Warfare (CoD4) when I joined some random Team Deathmatch lobby which ended up being hacked. I did not notice at first and killed the first guy I saw. This resulted in me earning some crazy amount of negative XP. I eventually left the game and tried to join another lobby but I am unable to select any type of lobby. I understand that Activision has stopped their support for this game, so I was hoping someone here could help me out. I don't play any other game and I really don't want to get a new gamertag, so if anyone has any ideas, please let me know! My gamertag is Jake DABS Jones, email is [email protected] and I'm playing on an XBox 360. Thank you!!! Any help will be appreciated.
