first, what version of software do you have? I have version 5, and I updated my install with the upgrade to 5.01, but you need to follow the install instructions to the letter (this update is for Win2k, but like others, i used it to install it to XP) if you go to the Roxio site:
http://www.roxio.com/en/support/ecdc/ecdc501s.jhtml, it will give you the links.
I would suggest, as would others, uninstall what you have now (i am assuming version 5), and reboot. then install version 5, with a custom option, and only install direct cd and easy creator, when that goes to finish the install, with a message box to reboot, DO NOT REBOOT. install the update to 5.01 (before you reboot from the first install). when that is finished, then reboot.
again, I have XP, and I am running RIXIO 5.01 with no problems.. yet...
