I just downloaded Toribash on another computer because the one I usually use is unavailable, but whenever I log onto my account, it doesn't load my account. It loads me as a default white-belt character, instead of my black-belt character. Why?

Because your textures are not saved in that computer. In singeplayer, type /dl Gbleek. It should work then. If not, you just have to wait, This usually happens to me.
