You'll need the latest version (69) of IC2 off the Jenkins, the version on Curse is a tad out of date so will cause that crash.
Thank you, That fixed it
Now i have problems with the impellerized roller. I give it 2V of power since it is what it needs and it drained some and stopped. Than i put a piece of iron to turn it into the plate. Nothing happens. No energy draining no indication that it is working.When i give it a redstone signal it changes its texture indicating it is working but in reality it does nothing.Funny thing is, after the signal it stucks regardless of any signal or power at working state of texture.Nothing happens when give it HU or KU.When i keep the signal on it drains exactly like it is completely pressurized with no load. Maybe I am missing something here maybe it is bug.
Edit:I have to add that it is happening only to the server with a fatal error in the bat window.
http://pastebin.com/9Vkjj9u1 this is me logging in playing with the roller and log off. on a single player world it works good.
PS: I tried every ingot possible still nothing.
PS2:Extruder Guy is acting exactly the same.
