Players booting Call of Duty: Modern Warfare 3 for the first time after the Season 1 update may encounter a frankly horrifying update alert - notifying players that all progress has been lost and must be reset. Especially for those who have put in the effort to complete the four weeks of pre-season challenges to unlock the golden river camo, along with anyone who has quickly maxed out their player level and reached level 55, this can be a heartbreaking error code to receive. Do not fret, as the resolution to such a disastrous error code is much simpler than players may assume.
