I installed a game through WUP Installer I'd already purchased from the eShop before, because I forgot it was already installed on my Wii U. If I deleted the game through system settings, the bad ticket that WUP Installer installed together with the game would still be there. Thus it wouldn't be possible for me to redownload the game from the eShop. How can I manually delete a ticket from my Wii U without formatting all the console? Where can I find the installed ticket files?
