Help needed Please

[Private Hudson]

Have just opened Launchbox and have this Error message. Has anyone encountered this before and what is the best way to fix this.

Any help would be very much appreciated.

Thanks Team.

This is typically caused when you first open up the app in the "Games Missing Media" sidebar filter. Change the filter before closing the app and it should correct this.

What does it mean when I get this message after trying to import a game?
