You don't by any chance have Roxio Easy Cd Creator 5 installed do you? If so, there's a program in there called Take Two that has caused enough problems that Adaptec has dropped the Take Two from their upgrade version 6.
If that'e the case you can either uninstall and do a custom install omitting the Take Two feature, or go to their website and install Version 6.
If this doesn't get it, or is not applicable, then we're going to need more info regarding your system, as much as you can tell us.
Hang in there. If I don't nail it, someone will
