Windows 8 Pro lost my cd/dvd drive on my Toshiba notebook

I recently downloaded Windows8 Pro on my Toshiba notebook. A Satellite C665D. It lloks like my cd/dvd drive is now inoperable and I cant seem to download an updated driver from Toshiba. I get this error message:

Windows cannot start this hardware device because its configuration
information (in the registry) is incomplete or damaged. (Code 19)

Can anybody help?
Thanks

I just added a Blu-Ray drive to my system, and it didn't work. The tutorial steps led to my system now seeing the drive. Thanks!
