What players need to know about Modern Warfare 2's "EXE/BAD CHALLENGE" issue

Due to a misunderstanding with their Vault Edition features, the Modern Warfare 2 developers recently gave out 10 double XP and 10 double weapon XP tokens to gamers. However, as soon as they tried to utilize these XP tokens, players discovered that they were being sent to the main menu and receiving the "EXE/BAD CHALLENGE" error message instead of staying in the lobby. The players who are most impacted by it are those who are playing the game on consoles from a prior generation, as was already mentioned. While players wait for Infinity Ward to fix the bugs, here are some possible solutions and workarounds:

1) Do not sit at the lobby screen

Prevent waiting on the lobby screen with all the other players. This is perhaps the simplest and most straightforward technique to avoid running into this problem. You can accomplish this by going to the Weapons tab and editing a class once you've begun the match queue. then hold on until the game starts there.

2) Rebooting the device and the game

Most of the time, a straightforward game restart can fix the issue. If the issue persists, try shutting completely down the computer or other device you are using to play the game. It is best to unplug the device for two to three minutes before turning it back on.

3) Verify any game updates.

Regularly checking for game and device software updates is always a smart idea. Infinity Ward has been aggressively issuing updates to ensure that the game's player base gets a refined experience. It is therefore suggested to keep an eye out for any prospective live updates. Follow these steps to accomplish this:

• By clicking the MW2 icon on the home screen, choose "Check for Updates" from the "Options" menu on Playstation.
• Choose "Manage" from the drop-down option under "My Games and Apps" on Xbox, and then choose "Updates."

4) Installing Modern Warfare 2 again

If nothing seems to be working for you, one or more of the game files are probably corrupt. Reinstalling the entire game is suggested in this situation as the last option. Although this is a potential solution, it is advised to hold off until Infinity Ward releases an update. These are some potential solutions to the Modern Warfare 2 EXE/BAD CHALLENGE XP bug. However, it is advised to get in touch with the Activision support staff if the issue still doesn't go away. On the PC, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series S/X, Modern Warfare 2 is accessible. It has cutting-edge AI, new audio technology, and improved graphics.
