If your settings, preferences or profiles are not saving and the MT4 platform will only load using the default settings, a common cause is a corrupt terminal folder. This can usually be fixed in one of two ways: 


You may need to uninstall the MT4 platform and then reinstall it. You can download the platform again either by finding the welcome email sent to you when you first opened your trading account or via the Fusion Hub; or 

  • Close the MT4 platform and locate the file named in within the ‘Configurations’ folder. Rename this file terminal. old and restart the application. This will generate a new terminal.ini file.
