For early versions of Minecraft, when using the default Minecraft Launcher, the options.txt file is incompatible and will cause the game to crash. To fix this, go into your .minecraft directory and either delete or rename the options.txt file (warning, completely deleting the file will cause your settings to reset across versions).
