I followed all the instructions and loaded the CD, but I got the black screen

Oh well, maybe my CD didn't burn correct, so I've been trying to eject it with no luck. I tried depressing the Eject button for 2 mins and pressing it again like someone earlier had done, and still no luck. I have a 04 M3. Can someone (PLEEASE!!) give me pointers on how I can eject??? Thanks!!!
