Gecko 201's help

Hi all!,
Just me again ,well.............I finally powered up the Gecko201's
but instead of the motors turning like they are supposed too they
were locked solid so to speak. I tried swapping the wires from pin
3to4 with each other and also the wires pin 5to6 with each other but
still the same!Well ,I know it must be the motor wires wrong but I am
afraid to try anything else without expert advice, as it was I turned
the power on with much trepidation! Oh by the way I tried it using
CNCpro evaluation demo program.
help please
Mark (the nervous wreck)
