How to Fix First Descendant Login Failed [LE:13] Error

Error [LE:13] is pretty much always associated with the Easy Anti-Cheat (EAC) system and will prevent you from logging into The First Descendant. It's also a repeat offender and might pop up on and off for a long period of time, across different game versions. Although this error is common with new game releases and some older games (after updates), it usually gets patched over time. But if you’re still facing the problem, follow these steps.

How to Fix First Descendant Login Failed [LE:13] Error

Restart the Game... YES!

Here's an all-time favourite working classic for you! This can resolve minor glitches that might be causing the error. Remember this legend of an IT quote! "Have you tried turning it Off and On again?" The same thing works for a lot of game errors. Especially live service games like The First Descendant.

Reboot Your System (Have you turned it off and on again?)

If restarting the game doesn't help, reboot your computer. This can clear out processes that may be interfering with EAC. It may seem basic, but it often works! Yeah, yeah I know! There's probably nothing you haven't tried already! But it's important to start with the little things!

Check for EAC Interference (This is the big one!)

Since EAC is the cause of the problem and a super important part of game security, it can be prone to interference and corruption from various sources. Restarting your system can help eliminate any conflicting background processes.

It's Probably EAC Issues...

If the quick fixes above don’t help with this issue, the problem might be more deeply rooted in EAC. Here’s what you can do:

• Search for the Error Code: Looking up error code 100011 can reveal that this issue is common across games using EAC, such as 7 Days to Die and Rust.
• Identify the Cause: The problem often arises because EAC is unable to write to your drive, potentially due to being blocked by antivirus software or other security programs.

You may find solutions for other games that can also help resolve this issue in The First Descendant. EAC is known for various quirks that can cause different problems.

Check Antivirus Settings (An Unlikely Issue)

Your antivirus software might be blocking EAC from functioning correctly. Try this.

• Temporarily Disable Antivirus: Turn off your antivirus temporarily to see if the issue is resolved. Ensure you re-enable it after testing.
• Check for Blocked Processes: Verify that your antivirus is not blocking EAC or any related game files.

Scan for Malware (An Unlikely Issue)

In some cases, malware or a rootkit on your system could interfere with EAC. Run a full system scan with a reputable antivirus program to check for any infections. I doubt this is the problem but it's worth a quick check.

Verify Game Files in Steam.

This is pretty much Standard Operating Procedure for modern games and will sort out any kinks and problems that may have found their way into the installation.

• Launch Steam
  
• Change to the Library tab.
  
• Find Soulmask, right-click on it and select Properties.
  
• Go to the Local Files tab and click "Verify integrity of game files".
  
• Wait for the process to finish. It takes a while sometimes.
  

Uninstall and Reinstall The First Descendant

• Drive Issues: EAC might struggle to write to your drive due to storage device issues. Check for any errors or issues with your drive.
  
• System Conflicts: Other software or system settings might conflict with EAC. Look into recent changes or installations that coincide with the error's appearance.
  

If none of the above steps resolves the problem, it might be best to reinstall both the game and Easy Anti-Cheat.
