If you, Like me, have wallpapers that you were downloading that were't showing up in the RainWallpaper UI, then this is the fix for you. All you need to do is download this updated file, then cut and paste it to your RainWallpaper folder. This will replace the .exe file of RainWallpaper and all of your downloads should become available to you.
