I was using a mod installer when suddenly it stopped working. so i uninstalled it and tried to do it again and i still wouldnt work. So then i uninstalled minecraft and reinstalled it and STILL wouldnt work. I even did a system refresh, reinstalled java and minecraft and still wouldnt work. I can still open minecraft but i cant play maps.
EDIT: Only Historical Versions Work.
ANOTHER EDIT: Versions 1.9+ crash the game instantly.
