You're using a shutter speed that's too fast.
Start at your camera's sync speed (1/250th on the D80, I believe). That may or may not work, as there's a bit of lag between the time the xmitter fires and the receiver fires the remote flash. If you still get a black bar, then go down to 1/200th or 1/160th and it should go away. Don't use a shutter speed higher than that.
