Old Version Error (4002, -62)

If you receive the following message:

You have been disconnected because you tried to connect with an old version. Application will now shut down. (code = 4002, -62)

as of now, there are 4 common causes for this problem:

• C++ 2015 (x86) is not installed
• d3dx9_43.dll is missing
• Windows Firewall, Defender, or antivirus deleted JFTSE.dll
• The game files are out of date

Fix 1: C++ 2015 (x86) is not installed

Install the Visual C++ Redistributable (x86):

Download C++ 2015 x86 Redistributable

Fix 2: d3dx9_43.dll is missing

If you receive an error saying that d3dx9_43.dll is missing, install the DirectX runtime:

Download DirectX End-User Runtime

Fix 3: JFTSE.dll was deleted

Windows Defender, Firewall, or third-party antivirus software may block, quarantine, or delete JFTSE.dll.

What to do:

• Check your antivirus quarantine
• Restore JFTSE.dll if it was removed
• Add the full game folder to your antivirus or Defender exclusions
• Make sure the anti-cheat files are not being blocked

Fix 4: Files are out of date

Always launch the game with:

FT_Launcher.exe

This will check for updates and download missing or outdated files.

User Already Logged In (4002, -2)

If you receive the following message:

This user id is currently logged on. Please try again later. (code = 4002, -2)

then your account is still marked as logged in on the server.

This can happen if the game did not close correctly, the connection was interrupted, or the previous session did not reset properly.

What to do:

• Wait a few minutes and try again
• Make sure the game is fully closed
• Restart the launcher and try again
• If the problem continues, contact the moderators through #support-ticket and click Create Ticket.

If you see this message, your account has not been confirmed yet and access to the game is denied.

For newly registered accounts, you must confirm your account using the registration confirmation email sent by JFTSE Security. This email may appear in your Spam folder.

Recommended Fix Order

If you are not sure what is causing the issue, try the following in order:

1. Install the C++ 2015 (x86) Redistributable
2. Install the DirectX runtime
3. Check whether JFTSE.dll was deleted or quarantined
4. Run FT_Launcher.exe
