I'ld uninstall Adaptec completely and reinstall. I don't know but it may have set itself up for your original cd burner and refuses to see the new one. A reinstall of adaptec may make it "see the light". Also I may have the 4.05 update on my HDD and if you gimme an e-mail (via IM if you want) I'll try to get it to (If I can I forget how big it is)
