Minecraft Forums

For a while now i have wanted to get xray. I know hacking is bad, but i want it creative mode for other resons. I have tried almose every different version of Minecraft 1.6.2 Xray but non of them work. I follow all steps correctly, then when i click play, it says Game ended with bad state (exit code 1). I know you say to delete the version and re-install but i have tried that and i really need xray for some videos im doing. Here is the full log:
