So i just got into COD and wanted to start with modern warfare. Got xbox live just to play. Been leveling up the past few days and got to 20. Then i went to play a game and after my game it said -5 million xp and i was at level 1. I thought it was a fluke and reset my console and waited a day. . Same problem and now it says i can''t get into any of the lobbies and they wont be unlocked yet. So what do i do? Been trying to find answers online.
