Recently I had taken out my SD Card to use a save editor for a game. Upon reinserting the SD Card, the custom theme was gone and all downloaded apps were missing. When using System Settings, the Sys prefix is still there. When attempting to use Data Mangment, a pop up saying "The SD Card software-managment data is corrupted. Reset it now?" appears. I've already made a backup of my SD card using Roadkil's Unstopable Copier , should I reset the data? Also when using FBI (through turning Download Play into Homebrew Launcher), selecting Titles pops up with "Failed to populate Title list". One thing that may have contributed was that I had edited my power off screen and updated without reverting it back to the original Home Menu CIA, but it worked just fine for a while.
