Nero 6 Multisession option gone...help please

I installed my new SOHW 812S as master with my old lite-0n 52x CDRW as slave.
When i started up nero 6.3.0.3, there is no option to create or continue a multisession either for cd or dvd. It also doesn’t give me an option to continue a multisession. Does anyone know why this is? Where has this option gone?
Does it have to do with the fact I now have 2 burners installed as master & slave or not?
Thanks for any help,
LA

Maybe you have to insert a disc to activate that option.

If you istall Nero 6.3.0.3 over a previous installation of Nero, then unistall it , and install it again.

does it recognize the 812 as a burner? if not it will not allow you to duplex write.
