i'm having issues launching Minecraft. When i go to launch it it opens the update screen but the bar doesn't move, so its not opening the game. there are times when it does open the game, but it doesn't have any of my saved worlds or multiplayer servers. In the files when i try to launch Minecraft it creates a new "minecraft" file with completely blank files and none of my saves.  the original file with all of my saves is still there but Minecraft wont open on it and i don't know how to fix it. the original file with my saves in under "Components" while the blank one is under "Application Support"
