Have got the enable pin (11) set correctly? if this is low this will act as a brake. Have you tried removing the Arduino and just hold the step wire to ground? this will test the motor and driver, when fault finding it is best to remove as many items as possible and rebuild piece by piece until the fault is found. Have you got all the grounds connected?
