So I made a post the other day about using the brazilian exploit to install a few games. All went fine with Minecraft and Mario Party 10. However today I tried installing Mario Kart 8. It installed ~2gb of the game before (I believe, because I wasn't watching the screen) error'ing out (therefore, I don't know what error it gave). I went into Data Management and my Wii U told me there is unneeded data, which I assume is the partial install of MK8. It asked if I wanted to Delete or Leave it for now, so I chose Delete, and now it's been showing "Deleting... Do not turn off the power" for a long time now. The blue circle is spinning around, but it's been on here forever, so I don't know if something is going wrong or if it really is being slow. What should I do?
