Mini_Cthulhu

Right im playing in my wolrd and ive built my smeltery and when i look at the controller block it comes up as invaild sturcture as sceenshot below the GUI looks like this I downloaded the tecnic launcher not long ago so i should be on the lastest patch and to note i cant run spacks texture pack because everytime i click to put it on the game crashes and shuts down

Yeah im getting a problem with it too, i downloaded the latest version because i only started playing this weekind 7/6/2014 and the smetery controll comes up like this, invaild stucture, so any ideas how to fix this
