Thanks for your help Francksoy,
Sorry I should have given my Model :doh: In CD-DVD it says [1:0] ASUS CRW-5224A 1.20
I just spent quite an amount of time on Nero's site trying to figure out exactly what is compatible with what as far as the utilities themsleves go and how dependant (if at all) they are with the "main program" . I'm also finding it a bit hard to find out exactly what my package entails but I know it is an OEM thing which came bundled with my Drive. On the disk it says nero5 Burning ROM in big letters, then in smaller letters it says V18.104.22.168 nero Express. I remember installing and uninstalling InCD as well.
Theres also little tools U can download to clean your system out properly (reg keys and stuff) for a re-install or upgrade.
From what I can gather, the Nero Toolkit is a seperate and freely updateable as in you don't have to pay for an upgrade, otherwise I wouldn't have been able to download it freely from this site, right?
I can't find anything on the site about what Toolkit is compatible with.
