Problem with power input for motor driver

http://jsumo.com/shop/genesis-arduino-robot-controller-board/

The power input of the "Genesis" motor driver (the link ^) is no longer working. Connecting it to a power source in the same way as always, the board shows no response. The + is to + and the - is to -, and the same set of things have been done consistently for many times now and each time, it's worked fine. So what happened here?

Are you sure the power source is working? Have you measured its output voltage with a multimeter?

Maybe the screw connector has become disconnected from the board - perhaps due to rough handling or poor manufacturing. Can you use your multimeter to test continuity between the connector and some locations on the board?

Yeah. The connector is disconnected from the rest of the board. How can I fix this without ruining the board?

I have no idea because I can't see the board with the problem.

Is it as simple as re-soldering the connector?
Perhaps the connector could be attached with a pair of flying wires - not elegant, but could be effective?

Can you show a clear photo of the back of the board where the connector is/was soldered?
Have the tracks been damaged, or is it just that the solder has let go?
