I woke up at a normal day and played minecraft. After playing minecraft, i went to my browser and randomly searched for ways to boost my fps. I went to a site and they told me to update to java 7. So I uninstalled Java 6 Update 35 and installed Java 7 Update 21. After that, I ｗｅｎｔ ｔｏ ｐｌａｙ ｍｉｎｅｃｒａｆｔ ｉｎ ｍｕｌｔｉｐｌａｙｅｒ. Ｈｏｗｅｖｅｒ, ａｌｌ
