If I'm not mistaken, and I'm pretty sure I'm not, the capx already has comments which state exactly what I changed.
But I took a look anyway.
The controls were on the layer "HUD" and that layer is referenced in the actions.
The controls are now on the layer "gold&exp" so the reference to "HUD" isn't working.
Make a new layer call it HUD place all controls on it and it should work.
