Overview

This page covers common problems and fixes for Fantasy Tennis.

If the game does not start correctly, shows login errors, or disconnects with version-related messages, check the sections below.

Common Issues

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  • The game files are out of date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:

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Fix 4: Files are out of date

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.
