Every time I go to download Minecraft 1.12 I get an error message like Unable to download. patchy-1.1.jar or az-az.lang or snow3.ogg and every time I try again it comes up with another error, it is only 1.12 though every other version will work fine. I have tried uninstalling it and .minecraft and it still will give me an error message. It will ask to show more and these are some of the things that it will say
