It could be a faulty flashgun or it could just be dirty contacts, try cleaning the contacts on the bottom of the flash foot and the ones in the flash shoe of the camera, a cloth dampened with some rubbing alcohol (isopropyl) or lighter fuel would be ideal.
The camera will keep displaying the message because this is the standard message you get when to try to adjust external flash settings with no flashgun attached.
