I tried to get a new skin, and I downloaded it, and then I applied the file to add a new skin, and the skin came up so I know that the computer could understand the file, but when I tried to save it it said unable to save and wouldn't work. I thought this was weird, so I tried to duplicate my old skin and that didn't work, so I deleted my old skin then tried saving the new one but that didn't work either—idk whats making it do that, but it's being really weird. It also won't let me duplicate the basic skins (Steve and Alex). I tried restarting my computer and opening up the launcher again but it didn't do anything.
