Have you tried reading the CD in another computer? If another computer can read it, you know the CD is OK and you need to clean your DVD/CD drive with an inexpensive kit you can buy from most places that sell computers. If no other computer can read the disc, then you know you just have to get another disc.
My Asus U81A's (laptop) CD-drive is not recognizing my Office 2010 Academic Trial CD. It does not show up in the D: drive on "My Computer." I do not see it anywhere! Help would be greatly appreciated!
