Hello, I tried to launch 1.2.5 today to play an adventure map but it kept on crashing when I launched it. I know it is a old version but I tried to uninstall and reinstall AND use other older versions of the launcher. Thanks in advance.

I didn't load the map, it's when I launch the game raw with no Optifine or anything.
