So I have a minecraft folder inside the application support folder, but here is the catch, there is nothing inside of it. Everytime I open Minecraft it sends me to the 1.3 opener, I can't log in at all and it says "not downloaded". I have tried trashing the minecraft folder and redownloading a new minecraft, it recreates itself with nothing inside once again. is there anyway for me to fix this? or for someone to send me there own files? is this even what is causing the problem?
