Someone sent us a CD with their invitation to their wedding. I put it in the computer and now it makes a noise, but nothing is happening. I am trying to eject the CD, but it will not eject, or stop with the noise like it is trying read and open the CD. In finder the eject will not highlight. Any help. We have 2.66GHz, Intel Core 2 Duo 4GB 1067MHz, Mac OS X
