I used to get this error every time i typed in-game, or just randomly every ten minutes or so. Some weeks were worse than others. In september it got so bad i couldn't even start the game; the launcher would freeze or i'll only get as far as "loading terrain" and I get the "Java Platform Binary SE Not Responding" error. I updated my GPU driver, and the game worked perfectly for 1 day then back to not working at all. Please help! I've tried reinstalling the game, reinstalling java 100000 times.
