Oh no, I'm sorry to hear it isn't working! Here are a few things to try.

1) Put your hand on the pump; do you feel it vibrating? The pump is super quiet, and it's possible that it is actually running but you just can't hear it. Try adding water and see if it moves.

2) Check the data plate on the pump and make sure that blue is still positive and brown is still negative, maybe they changed it?

3) If you have a volt meter, measure the voltage between red and black to make sure it's at least 3.3v.

4) If you're using a 3.3v power supply, try a 5v power supply. 3.3v is right on the edge of the minimum the pump requires... maybe you have a pump that needs just a bit more voltage.
