So I have installed the 1.7.5 files in my World of Minecraft client folder . then I have started a multiplayer game and wrote /client because I want to see what they are (oh bad gramatikary Oo??). I have used them all to see what they are doing . SO I have used "/client ui off" and I havent got an chat and some more things was strange . I deleted ALL files and folders in my World of Minecraft folder , and reinstall World of Minecraft (I used the files and folders from the .zip) . I started the World of Minecraft.exe , logged me in , started a game - and havent got a chat , again . (when I press "t" I release the mouse .)
