I would advise ignoring the Roxio suggestion. There are at least 5 packet writing file systems which do not coexist well--Roxio and InCD are among the worst and IMHO Roxio/Adaptek is at the bottom. In addition many burner programs--every slideshow claimant--fight among themselves for the driver/file association settings on our desktops. Keep checking with Nero info tool to see which drivers/aspi files are installed. If you must use packet writing, you might try NTI's. They are Sonic's, as I remember, but I think derived from DLA, not Roxio/EZAdaptek. And NTI is at least candid and helpful enough to have this among their FAQ's:
CD&DVD-Maker Frequently Asked Questions
"After installing CD Maker 2000, my system locks up or will only boot in Safe Mode. "
"This problem is a device driver conflict that can be corrected by renaming the files listed below. If you want to continue using EZ-CD/DirectCD software NTI also recommends you to reinstall the CD Maker 2000 software first, then install Adaptec?s software, after renaming the files.
Rename all the other files and this should correct the issue.

This applies to locking up, but many of the same conflicts interfere in the kind of situation suggested by the complainant. Be sure you add the InCD drivers if you are trying to clear these. Use the Nero Cleaning Tools including the InCD cleaning tool, before re-installing all, not just re-naming. And of course, RoxioZap.exe.
