MTA file version mismatch or incompatible network module

Replace mixed client files with one complete current installation.

Codes on this page: CL40

Steps

Try one step, then check whether the problem is still there. Follow any "only if" line before changing a setting.

1. Close every running MTA instance

   Stop the launcher and game before replacing client files.

2. Install one complete official release

   Run the current official MTA installer for the installation you use. Do not mix netc.dll or other modules from old downloads with a newer client.

3. Check that your shortcut opens that copy

   Retry from the updated installation. If it still reports a mismatch, include the complete module name and displayed versions in a support request.
