BlinkM MaxM - all 3 LEDs light up - no further response

This week week I received my order of two BlinkM Maxm and four Blink through Sparkfun.

I seem to have a problem with one of the BlinkM MaxM.

When connecting this one to the Arduino board, all three LEDs light up however no further response.

The other one and the BlinkMs seem to work fine

Using the BlinkMTester example there is no response from the BlinkM MaxM board. Also using the BlinkMCommunitor in combination with the sequencer does not work for this BlinkM, while both methods work with the other BlinkM boards.

I have tried both the configuration using power from the Arduino board as well as a external stabilised 9V supply.

Do you know how to correct for this or does this indicate a defect?

Thanks for your support,
