Using your fingernails pull it straight out and you'll see. Is the shoe on the M4 a hot shoe? if not, check to see that you don't have a bad flash cord. Take your camera down to your local shop and try a brand new manual flsh unit. Between these two tests you should be able to eliminate the bad piece of gear (cord or flash). If neither is bad it's your camera.
