I recently installed Duox2 Cromwell and everything was working fine. But my eject button doesn't work. It hasn't been working since i installed the modchip.Is there anything i can do to fix this?

Check your Bt point.

you prob. just bridged the points on the back of the eject board.

check it out, and fix/replace if needed.
i sell them in my store, and i've got a sale this week.
