External CD adapter not ejecting CD

Hello. I put in a blank CD into my disc adapter to burn music onto my CD (a blank one). I cancelled the burning during the process. Now it won't come out of the adapter. My MacBook Air's eject button will not work. I've tried command E, reseting/shutting down, logging out, unplugging the adapter but all that happens is the CD spinning then stopping over and over. Any ideas as to how to remove the CD?
