Ultimaker² not working

[kcanham 0]

Just unpacked the new Ultimaker² and watched the videos, plugged everything in as suggested, but the rotary button at the front does not move beyond the first screen for the initial set up. I assume the button does not work. it lights up so I have power, any suggestions. does the machine have a reset code I can enter?

Can you take a video showing the push action and rotate action? The knob should push and you should hear a click sound from the computer (a short beep).

The screw holding the knob may be loose. It all comes apart starting with the cover at the bottom - don't try to remove any of the large panels - no need for that. There's assembly instructions in a large PDF somewhere that shows exactly how to put together a UM2.
