Clicker wheel stopped clicking

[eric-rea 2]

I just got my new U2 and was ecstatic to began printing. However a few minutes into navigating the lcd display with the little wheel, the wheel stopped clicking. It will rotate but not click.

It seems that the wheel has come loose from it's shaft. We took off the panel underneath the chip board that the wheel is attached to but cant pull the wheel through the opening to tighten it because the bezel is wider than the opening I think.

Can anyone shed light on this fix?

Thanks!

Heres a pick of the wheel.
