Do you have a backup?
Product key for for MS products is not on the CD..
Not necessarily, alot of things get packaged differently for different countries. My Office 2007 had the product key printed on the front of the CD itself.
(I remember, quite clearly, opening the case, putting the CD in the drive and looking everywhere on the CD case for the product key. Plenty of head scrathing, then had a 'DOH' moment when i took the CD out of the drive, to take it back to the shop, and put it in the case, only to have the 'key' staring at me from the front of the CD)
