The CD will not eject in my Jensen CD4010K car stereo?

I just used the CD, wanted to eject it to use another, and I pushed the button, it came part way out, like normal, then went back in and will not eject. The eject button is lit up red and I cannot even play the CD now. I have turned the stereo off and back on, same problem, even turned the car off hoping that would help. Also it seems pretty warm, which it would do if I had been playing a CD.
