Follow our easy step-by-step guide to How to Fix Texas Chainsaw Massacre Supplied Credentials are Invalid issues quickly.

Welcome to our friendly guide on fixing the "Texas Chainsaw Massacre Supplied Credentials are Invalid" error. If you've encountered this frustrating issue, fear not! We have some simple steps that can help you get back into the game in no time.

Step 1: Restart your system


Sometimes, a simple system restart can work wonders. Close any running applications and restart your computer. This can help refresh system settings and resolve minor software glitches that might be causing the credential error.

The first step in troubleshooting any error is to restart your system. This helps clear the system's cache and refreshes various settings. To restart your computer, close all running applications and click on the Start button in the bottom left corner of your screen. From the Start menu, select the Power option and click on Restart.

After your system restarts, try launching the game again and see if the error persists. If the error still occurs, proceed to the next step.

Step 2: Change Windows Region Settings


In some cases, incorrect region settings may be the culprit behind this error. Follow these steps to change your Windows region settings:
  • 1. Press the Windows key + I on your keyboard to open the Settings menu.
  • 2. Select "Time & Language," then go to the "Region" tab.
  • 3. Make sure that your region is set correctly. If it's not, click on the drop-down menu and select the appropriate region.
  • 4. Restart your computer and try launching the game again.

Incorrect region settings can sometimes cause credential errors because the game might be designed to only work with specific regions. By adjusting your Windows region settings, you ensure that the game recognizes your location correctly.

Step 3: Change Windows Keyboard Options to ENG-US



An incompatible keyboard layout can sometimes trigger credential errors as well. To change your keyboard options to ENG-US, follow these steps:

  • 1. Press the Windows key + I on your keyboard to open the Settings menu.
  • 2. Select "Time & Language," then go to the "Language" tab.
  • 3. Under "Preferred languages," click on "Add a language."
  • 4. Search for "English (United States)" and click on it to add it.
  • 5. Set English (United States) as your default language by clicking on it and selecting "Set as default."
  • 6. Restart your computer and try launching the game again.

Some games are designed to work specifically with certain keyboard layouts. By changing your keyboard options to ENG-US, you ensure compatibility with the game you're trying to play.

Step 4: Enter Your Credentials on the Launcher


After implementing the previous steps, launch the game and enter your credentials on the provided launcher. Ensure that you are typing in the correct username and password associated with your game account.


Sometimes, the credential error might be caused by a simple typing mistake. Double-check that you are entering the correct username and password, paying attention to uppercase and lowercase letters. If you're unsure about your login credentials, try resetting your password through the game's official website.


By following these friendly steps, you should now be able to fix the "Texas Chainsaw Massacre Supplied Credentials are Invalid" error and enjoy uninterrupted gaming sessions. Remember to restart your system, adjust Windows region settings, change keyboard options to ENG-US, and enter your credentials correctly. Happy gaming!



In conclusion, encountering the "Texas Chainsaw Massacre Supplied Credentials are Invalid" error can be frustrating, but with the right steps, you can resolve it quickly. By restarting your system, changing Windows region settings, adjusting keyboard options to ENG-US, and entering your credentials correctly, you should be able to overcome this error and get back to enjoying your gaming experience.
