This simply refers to some data that was not properly cleaned up in your console. It is always a good idea to perform a clean start whenever loading a new show. To do so on a Wholehog 2 console, press the reset button. On a Hog 500/1000 hold ENTER while powering on the console and select "clean start" from the menu.
Be sure your show is backed up prior to the clean start as this will erase the current show in memory.
