Potential solutions for Delta Force Login failed Id 4/35 error

1) Delete your session files

Occasionally, the session files that Delta Force generates at login can become corrupted, particularly if the game crashed previously. These files can prevent you from logging back in.

Here’s how to resolve it:

• Head to where the game is installed on your computer.
• Go to: Delta Force\Launcher\Cache\TSF4G2
• Remove everything within that directory. Then, try launching the game again. This will cause it to generate new session files, which usually cures the Login failed Id 4/35 problem.

2) Reinstall or check the game launcher

Glitches and missing files occur. In case something is faulty in the installation, Steam will be able to repair it.

• Right-click Delta Force in your Steam library.
• Click Properties > Installed Files > Verify integrity of game files. Steam will scan for anything that's out of place and repair it. If it still doesn't work, a reinstallation of the game launcher may solve the issue.

3) Restart Steam

Perhaps the problem isn't the game; it may be Steam itself. Occasionally, Delta Force simply can't get connected to Steam.

• Close Steam fully from the taskbar or Task Manager.
• Open it back up and attempt to start Delta Force again. This resets the connection and usually resolves the Login failed Id 4/35 issue.

4) Monitor your firewall or antivirus

Despite its best efforts, security software can occasionally cause problems. Delta Force may not be able to connect to the internet because of your firewall or antivirus software. Try temporarily disabling your antivirus software or adding the game to the list of exceptions to see if that resolves the issue.
