Can you help me how can i play?

tekkit's version:3.1.2

you have a block conflict. ic2's scaffold block is trying to assign itself to block ID 216, but computercraft has already taken it for the turtle. if you changed something in IC2's config and made a mistake, i think IC2 deletes the config and generates the default.
