How to replace extruder nozzle?

I need to take the nozzle off of the extruder to see if there are any clogs in there. I have a replacement if necessary (came with the printer so it won't change much). I took out the screw in the unit holding the nozzle, but I can't get the nozzle itself to budge. Is there some secret to this?

    so you just want the nozzle (brass) off right?
    you can heat the heatblock to make it somewhat expand a little. Or heat it till any filament stuck between the threads burns off. while heating, carefully unscrew the heatblock (DO NOT FORCE IT). 
    -do not heat it too much or metal will degrade and becomes brittle.
    -do not force the nozzle, it should unscrew easily.

    also Youtube has an official video posted by the manufacturer on how to replace the extruder nozzle.
