To reset the data source go to the application installed directory; similar to C:\Program Files\Mangofile\Mangofile Software Level\DMS.exe.

Hold down the F12 and launch the application from DMS.exe (Window 7 users will need to right click and use 'Run as Administrator' while still holding down the F12 key).

If done correctly, you will see the same window as you would have seen when first setting up Mangofile, and setting the Data Storage location to point to your Mangofile 'data source'.

Check and change the Data Storage location to the correct location (ask your local admin for details) and press the check button to the right of the path/text box.

The settings will not update and take effect.

If the box appears again, change the settings once more but press the F12 key again to release this function, and press check.
