Hi, I'm new here and I have a question. I use Wii u Usb helper to download games, i put them on the sd card and till here all goes good without problems, then i insert the sd card back at the Wii u and the games doesn't show up on WUP installer, i put the sd card back at the PC and the contents of the game's folder are gone, why does this happen? (it didn't do that before but now it does)
