Thank you for your reply. I did try removing the upper & lower filters,
as suggested by Microsoft, but I still get the same message. I am now
suspecting a hardware issue, as I am now hearing a clicking sound as the
DVD drive tries to start-up. Considering that I've only had this
computer for about a month, I'd hate to think that the DVD/CD drive has
completely stopped working and will need to be replaced....but that
appears the case.
