Why does Minecraft PC keep crashing?
Added (1). I have two mods loaded, one is Rei's mini-map and the other is the Lord of the Rings mod. And the last time I played, this message popped up that said that I should make a backup of the game, well at the time I didn't know what that was, and I didn't know how to do it. So I ignored it and kept playing, now the game keeps crashing. Can you help how to fix it?
