I attempted to install some software using a CD, but when I push it in, it won't go all the way and it spits it out. I don't recall using the DVD player for quite a while. When I try to use "Command-E" to eject, nothing comes out. I used the "eject" icon on the wireless keyboard, but nothing happens. I used the eject function on the DVD window, but again, nothing. The desktop doesn't show an icon that there is something in the slot. I have a wireless keyboard and mouse, so its difficult to restart and press "C" since it shuts down with the imac and turns on after the imac is loading. Can anyone tell me what's going on and is there something I can do? I have the OS 10.8.3. Thanks for your assistance.
