You can not "access" an empty CD. You either need to burn something to it or format it with InCD or an equivalent. InCD and it's variants come with Nero, Roxio, built into Windows on latter service packs. These programs must be installed to work, and they may have been omitted when you installed your burn software.
To verify the drive recognizes a DVD/CD blank and can work with it Nero (and probably Roxio) have utilities to check the blank. Or you can download freeware that will read a blank, I think CDINFO or DVDINFO is one name.
