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- The game files are out of date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:
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Fix 4: Files are out of date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This will check for updates and download missing or outdated files.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 @ModMail
