MW3 Your Data is Corrupt or Didn't Download Properly Fix

An unfortunate fact of online games is that they are very prone to connectivity issues and errors. This is also the case with Call of Duty: Modern Warfare 3, where you can get a very problematic error. It reads: “Your data is corrupt or didn’t download properly. You must reset your rank and unlocks to continue. [Reason: NIAMEY – LOGAN]”. But what does this mean and do you really need to lose all of your progress in the game if you want to continue playing it? We are going to take a look at why the Your Data is Corrupt or Didn’t Download Properly error is occurring in CoD MW3 and whether there is anything you can do to fix this issue.

How to Fix CoD MW3 Season 1 Your Data is Corrupt or Didn’t Download Properly Error

To begin with, it depends on which gaming platform you are getting this error. If you are receiving it on the PS5, the devs recommend that you open up Quick Settings (via the options button) and then immediately exit these settings. Doing this should get you back to the correct menu and enable you to continue playing the game. Now, as for PC users, it doesn’t appear that there is a reliable solution for this. At least, not yet. Hopefully, there’s going to be a fix for the PC soon. Since Season 1 is currently underway, odds are good that the devs are going to tackle this problem and come up with a method to fix it as well.

This error has been around for a while now (it’s been a part of CoD MW2 as well), and the devs still haven’t addressed it on the PC. However, the good news is that the odds of you actually losing all of your progress are very low. While the error message looks very concerning, there’s no cause for alarm. The best course of action is to simply wait it out, since issues such as this usually crop up whenever there is a new update to the game. And in case the problem is persisting, you should contact CoD MW3 support for further assistance.

UPDATE: Now that Season 1 has started, players are greeted with the same “Your data is corrupt or didn’t download properly. You must reset your rank and unlocks to continue. [Reason: NIAMEY – LOGAN]” message. You are then presented with the option to select Yes or No. If you select no, you’ll get the following message: “Error. You cannot continue further without resetting your data. Please close the app, launch it again and answer “Yes” when you’re asked to reset your data.” As no one wants to get all of their unlocks and rank reset, what is the correct option here?

Well, according to this official Tweet: “Players logging into Season 1 may see an incorrect error message stating their data is corrupt. Rest assured that your rank, unlocks, and purchases are not lost, although Loadouts, customization, and certain settings may be reset.” Several players have reported that selecting “Yes” only erased their loadouts and that their ranks and unlocks are all fine. Still, as this is obviously a bug, it may be best to wait for a while until the devs have fixed it on their end.
